Abstract:
Limbah cair industri tekstil mengandung zat warna dan logam berat. Remazol Red RB dan logam kadmium merupakan zat warna dan logam berat yang banyak terdapat pada limbah tekstil. Pembuangan limbah cair tekstil tanpa pengolahan limbah terlebih dahulu akan menyebabkan pencemaran lingkungan perairan. Metode elektrolisis, fotokatalisis dan elektrofotokatalisis merupakan metode yang dapat digunakan dalam penanganan limbah tekstil. Pada penelitian ini akan dibandingkan ketiga metode tersebut untuk dekolorisasi larutan zat warna remazol red RB yang mengandung ion logam Cd2+ serta mengetahui pengaruh keberadaan ion logam Cd2+ dan penyinaran lampu UV-C terhadap dekolorisasi zat warna remazol red RB. Hasil penelitian menunjukkan bahwa metode elektrofotokatalisis merupakan metode yang paling efektif karena mampu mendekolorisasi remazol red RB hingga 97,85% dan menurunkan konsentrasi ion logam Cd2+ hingga 96,50%. Keberadaan ion logam Cd2+ dan penyinaran lampu UV-C meningkatkan dekolorisasi zat warna remazol red RB.

Abstract:
Kandungan ikatan azo dalam zat pewarna tekstil remazol red mengakibatkan zat warna lebih mudah larut dalam air dan memiliki stabilitas yang tinggi. Hal ini menyebabkan limbah tekstil memerlukan penanganan khusus agar aman dan tidak memberikan dampak negatif ketika dilepas ke perairan. Salah satu cara alternatif untuk menangani limbah non-degradable adalah dengan menggunakan metode fotodegradasi dengan bantuan fotokatalis. Penelitian ini bertujuan untuk membandingkan aktivitas reaksi fotodegradasi remazol red dengan fotokatalis TiO2 anatas 50%-rutil 50% dan TiO2 anatas tersupport AgI. Proses fotodegradasi Remazol red dilakukan dengan memvariasi fotokatalis yang digunakan yaitu fotokatalisis TiO2 anatas 50%-rutil 50% dan TiO2 anatas tersupport AgI dan lama waktu penyinaran yaitu 15 menit, 30 menit, 45 menit, 60 menit, 75 menit, dan 90 menit. Untuk mengetahui pengaruh lama penyinaran terhadap fotodegradasi Remazol red, maka dilakukan pengukuran absorbansi larutan menggunakan spectronic 200 pada panjang gelombang 558nm setiap selang waktu 15 menit. Hasil aktivitas fotokatalitis menunjukkan persentase degradasi remazol red pada sistem TiO2 anatas tersupport AgI, TiO2 anatas 50%-rutil 50% dan tanpa katalis berturut-turut sebesar 32%, 16%, dan 7%. Oleh karena itu fotokatalis TiO2 anatas tersupport AgI memiliki aktivitas fotokatalisis yang lebih baik daripada fotokatalis TiO2 anatas 50% - rutil 50%

Abstract:
Research on chitosan application as a natural coagulant in reducing the concentration of remazol red dye from batik liquid waste has been carried out. This study aims to study the effect of the acidity of batik wastewater on the coagulant ability to reduce the remazol red dye concentration and the COD value of batik liquid waste. In this study, chitosan compounds before and after coagulation were characterized using Fourier Transform Infrared (FTIR) Spectroscopy. The pH range used in the coagulation process was pH 2-6. Post-coagulation chitosan FTIR spectra showed a shift in the wave number in the 3400 cm-1 area, which indicated an interaction between the -OH group of chitosan and the dye remazol red. Remazol red dye was maximally coagulated by chitosan at pH 2. The percentage reduction in the dye concentration reached 100%, and the decrease in COD value at that pH was 71.69%.

The textile dye waste is a liquid waste that is difficult to oxidize and dangerous for the environment. Hydroxyl radicals (• OH) are very effective species in oxidizing various organic liquid wastes such as Remazol Red. Plasma Electrolysis Method is very productive in producing Hydroxyl radicals, resulting in effective degradation of various types of textile dye waste such as Remazol Red. This study aims to optimize the degradation process of remazol red RB 133 and its energy consumption using the Plasma Electrolysis method through temperature regulation and injection of air bubbles in solution. The formation of H2O2 is used an indicator of the formation of •OH in the Plasma Electrolysis reaction. The Air injection decreases the electric current on the current-voltage characteristic curve. The solution temperature increases from 45oC to 75oC for 10 minutes reaction without air injection were able to reduce the energy consumption from 229.9 kJ to 219.5 kJ and H2O2 production from 4.8 mmol to 3.1 mmol. Meanwhile, the addition of air injection at 75oC within 10 minutes of reaction were able to reduce electricity consumption by 28.5% and increases H2O2 production by 27.3%. However, the addition of air injection only increased the degradation of Remazol Red by 1.8%. The optimum temperature was reached at 55oC, with H2O2 production of 5.7 mmol for 30 minutes. The addition of air injection has been shown to increase the effectiveness of the process.

Abstract:
Toxicity tests using Sacharomycces cerevisiae were made with simulated textile effluents containing reactive dye (remazol red brilliant) treated by photoeletrolytic process, varying treatment time and applied current. The treatment incorporated an electrolytic reactor with rectangular titanium anode coated with 70% TiO2/30% RuO2 cathode and a rectangular stainless steel coupled with another photolytic reactor containing a high power UV lamp. The treatment system was used in batch recirculation, in other words, the simulated effluent was driven by the system through a helical pump. It was observed that the higher the value of current applied, the longer the treatment has greater color removal of textile effluent and higher mortality of S. cerevisiae, killing up to 100% of the cells at the end of the treatment. With a lower current applied and having the treatment time of 5 minutes, the effluent showed a color removal of 97% and a lower mortality of S. cerevisiae than the effluent simulated without any treatment.

Abstract:
Remazol Red B is a reactive dye that is often used in the textile industry. The dye can cause serious problems in the environmental / water because it is difficult to be degraded by microorganisms. Decolorization of reactive azo dyes (Remazol Red B) before being discharged into the environment is an important aspect in creating technology (method) that are environmentally friendly. The method chosen for this decolorization is Advanced Oxidation Process (AOP) using the Fenton reaction. The optimum conditions for this reaction is 25 mg/L H2O2 and 1.25 mg/L of Fe2+ to Remazol Red B with initial concentration at 83 mg/L ( with ratio [H2O2]/[Fe2+] = 20). The optimum conditions of this reaction were obtained at pH 3 and temperature of 27 0C, with decolorization efficiency up to 100% for a reaction time of 60 minutes. The kinetic model of dye decoloritation follow the second order reaction. Some of the metal ions were added i.e. Cu2+, Pb2+ and Zn2+ , given no significant impact on the degradation performed.

Abstract:
In this research, the adsorbent material was developed from the agricultural waste, tamarind-seed testa. The adsorption of 6 different reactive dyes viz. Procion Red H-E7B, Procion Yellow H-E4R, Procion Navy H-ER, Remazol Brilliant Red F3B gran, Remazol Yellow 3BS-A 150% and Remazol Black B 133%, on the adsorbent prepared from tamarind-seed testa was investigated. The chemical composition analysis showed that the major components in the tamarind-seed testa were lignin and carbohydrates (cellulose and hemicellulose). When the bleached tamarind-seed testa was used as an adsorbent, it was found to efficiently adsorb the reactive dyes at pH 2 without any assisting mechanical agitation. The reactive dye exhibiting ultimate adsorption on the adsorbent was Procion Navy H-ER (66.3 mg/g). A high rate of dye adsorbed capacity was noticed in the first hour and the equilibrium adsorption was reached within 3 hours.

Abstract:
Due to the large amount of wastewater discharged by the textile industry, many alternative researches have been undertaken in recent years to effectively remove textile dyes from water. In our study, the adsorption from aqueous solution of two important textile dyes, reactive azo dyes Remazol Red (RR) and Remazol Blue (RB) was studied with calcined chicken eggshell (Gallus Gallus domesticus) adsorbent. Batch biosorption studies were conducted to evaluate the effect of various parameters, such as contact time, initial dye concentration, amount of adsorbent, and pH, to determine the optimal adsorption parameters (Remazol Brilliant Red F3B: Ci=20 mg/l, 1.5g adsorbent, 160 μm, 700 rpm, pH=6.0�0.2, T=20�2 oC, where E%=97.3; Remazol Brilliant Blue R: Ci=20 mg/l, 1.5 g adsorbent, 160 μm, 700 rpm, pH=6.0�0.2, T=20�2oC, where E%=98.8). The changes in morphological structure were evaluated by SEM analysis. The experimental isotherm data were analyzed using the Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherm models. Biosorption kinetics data were tested using pseudo-first-order, pseudo-second-order, where in our experimental conditions the biosorption followed a pseudo-second-order reaction. EDS analyses were carried out, and bioconcentration factors were calculated before and after adsorption. The results of this study indicate that adsorption with calcined eggshell is a promising, feasible, reliable and eco-friendly method for Remazol textile dye removal from aqueous solutions.

Polymethyl methacrylate (PMMA) and pluronic 123 (P123) were used as the soft templates and co-templates for assisting the formation of hierarchical 3D porous structures. The TiO2 crystal structure, morphology, and Remazol red dye degradation were investigated. The 3D-HPT and normal three-dimensional titanium dioxide (3D-T) presented the good connection of the nanoparticle-linked honeycomb within the form of anatase. The 3D-HPT structure showed greatly enhanced adsorption of Remazol dye, and facilitated the efficient photocatalytic breakdown of the dye. Surprisingly, 3D-HPT can adsorb approximately 40% of 24 ppm Remazol dye in the dark, which is superior to 3D-T and the commercial anatase at the same condition (approx. 5%). Moreover, 3D-HPT can completely decolorize Remazol dye within just 20 min, which is more than three folds faster than the commercial anatase, making it one of the most active photocatalysts that have been reported for degradation of Remazol dye. The superior photocatalytic performance is attributed to the higher specific surface area, amplified light-harvesting efficiency, and enhanced adsorption capacity into the hierarchical 3D inverse opal structure compared to the commercial anatase TiO2.

Abstract:
Water based Remazol Brilliant Red, Orange and Violet dyes were used as the dye sensitizer in dye-sensitized solar cell. The performance of the solar cell was investigated between the dye concentrations, 0.25 mM and 2.5 mM and three different soaking times which at 3 hours, 12 hours and 24 hours. The adsorption peaks of the dyes were observed using ultraviolet-visible-near infrared (UV-Vis-NIR) Spectrometer and the performance of the dye-sensitized solar cell was measured using Spectrum Parameter Analyzer (SPA). The results show that the device efficiency was increased with dye concentration, but, the DSSC performance at different soaking times performed differently with the previous study. The highest conversion efficiency of 1.125 % was obtained for Remazol Brilliant Red at concentration of 2.5 mM at 3 hours soaking time.

Abstract:
Chitosan has been used as an adsorbent to remove remazol red RR from aqueous solution by adsorption. The experiments have been conducted to study the effects of initial concentration of adsorbate, temperature, pH and particle size on dye adsorption. The kinetic data obtained have been examined using pseudo first- and pseudo second-order equations. The equilibrium adsorption data have been studied by using Freundlich and Langmuir models. The best results have been achieved with the pseudo second-order kinetic model and with the Langmuir equilibrium isotherm model. The equilibrium adsorption capacity (qe) of chitosan increases with increasing the initial concentration of dye, temperature and with decreasing particle size. However, the highest adsorption capacity has been found at a pH about 5.4. The maximum monolayer adsorption capacity, qe = 155.72 mg/g has been found at the optimum conditions. The activation energy (Ea) of sorption kinetics is about 9.25 kJ/mol. Thermodynamic parameters such as change in free energy (?G), enthalpy (?H) and entropy (?S) have also been evaluated.

Abstract:
One of the most important manufacturing industries in Malaysia is textile and specifically batik making. Many local batik factories discharge their wastewater, which contains wax, resin, silicate and dyes, without treatment, directly to nature. A possible treatment system involving membrane filtration has been tested to remove the dyes. However the presence of wax the wastewater requires a pretreatment stage to remove the undesired wax. In this study the performance of baffle tank pretreatment (own designed and fabricated) was evaluated for 4 different types of synthetic batik wastewater, which contain wax, resin, sodium silicate and 4 different fibers reactive dyes namely, Remazol Turquoise Blue G133 (Blue 21), Remazol Red 194 and Remazol Yellow 14 and Reactive black 5. The removal efficiency (%), pH and COD of each sample were evaluated and recorded. Wax removal efficiency in all samples was more than 88%. The COD and pH of all samples decreased after 60 minutes pretreatment cycle.

Abstract:
Adsorptive removal of remazol red R (RRR) and remazol black B (RBB) from aqueous solution has been investigated by using ZnO as an adsorbent. Time for adsorption equilibrium, kinetics of adsorption at different initial concentrations of dyes and adsorption isotherms at different temperatures have been studied. Adsorption capacity increased with increasing initial dye concentration. The pseudo first-order and pseudo second-order kinetics were used to describe kinetic data and the rate constants were evaluated. Experimental data fits better in the pseudo second-order kinetic model than in the pseudo first-order kinetic model for both the dyes. Langmuir and Freundlich isotherm models were applied to describe the adsorption of RRR and RBB onto ZnO powders. Langmuir isotherm model provided a better correlation for the experimental data in comparison to the Freundlich isotherm model. Adsorption of both RRR and RBB on ZnO are physical in nature and increases with decreasing temperature. The equilibrium adsorption capacity decreases from 3.43 mg/g at 200C to 2.36 mg/g at 400C for RRR whereas that in the case of RBB changes from 0.77 mg/g at 300C to 0.75 mg/g at 400C. Adsorption of RRR on ZnO was found to be three times higher than the adsorption of RBB at a particular temperature. A model for adsorption of both the dyes has been proposed.

Abstract:
Advanced engineering of naturally occurring materials opens new doors in nanoscience and nanotechnology for the separation and/or removal of environmental hazards. Here, a series of nanocomposites containing kaolinite and chitosan varying in the range of 20 to 80% (w/w) kaolinite were used for the adsorptive removal of a reactive textile dye, Remazol Red, from an aqueous solution. Batch experiments were carried out to investigate the effects of pH, contact time, and initial dye concentration on the adsorption capacity. Nanocomposites containing 80% kaolinite (w/w) and 20% chitosan (w/w), i.e., NK80C20, showed an equilibrium adsorption capacity of 371.8 mg/g at pH 2.5, which was 5.2 times higher than that of commercial activated charcoal. Moreover, NK80C20 was regenerated instantly up to 99.9% at pH 10. Therefore, NK80C20 can be effectively utilized as a potential adsorbent for the separation of Remazol Red and homologous azo dyes from industrial effluents. We expect that the findings from this study will play a vital role in environmental research leading to advanced applications in water purification.

In this paper, the use of a clay residue as an adsorbent of the Remazol Black B (RB) and Remazol Red RB133 (RR) is studied. The residue is generated in a large amount on the Alluminum industry, especially the Arconic Alumínio S/A, Itapissuma, Pernambuco State. The thermally treated residue behavior was studied by performing a kinetic and equilibrium experiments. The variables evaluated in all experiments were the adsorption capacity (q) and adsorption efficiency (%). Adsorption experiments were performed at environmental conditions, with 50 mL of dye solution, with controlled steering speed, solution pH and adsorbent amount. In the kinetic studies was verified that for RB and RR, the system achieves the equilibrium state after 5 min. In the equilibrium, both reactive dyes obtained their maximum adsorption capacity (qm) with 1.0g of adsorbent and pH 4.0 and 6.5; with qm 0.98 mg·g-1 and 6.88 mg·g-1 for the RB and RR, respectively.

Abstract:
Potassium dichromate modified TiO2 photocatalyst (MD-TiO2) was prepared and its photocatalytic activity was compared with that of ordinary commercial TiO2 (C-TiO2) and special Degussa P25 TiO2 (D-TiO2). An organic dye, remozol red R(RRR) was used as a substrate for photodegradation from aqueous solution into environmentally safe products such as water, carbon dioxide and mineral ions. The photodegradation of RRR was carried out by varying the concentration of different types of TiO2 suspension, initial concentrations of dyes between 0.5× 10-4 M and 2.5 ×10-4 M, pH between 2.0 and 6.0 and light sources which are UV, artificial visible and sunlight. With increasing the catalyst concentration, percent degradation was found to increase up to a concentration of 1.2 g/100 mL of C-TiO2, 0.12 g/ 100 mL of D-TiO2 and 0.10 g/100 mL of modified MD-TiO2 for a definite concentration of RRR. However, RRR shows adsorption on TiO2 samples except C-TiO2. Again, the photodegradation efficiency is inversely affected by the dye concentration. Thus, the removal efficiency was found to be influenced by all of the above parameters. The maximum removal efficiency is found at pH 3.0 under sunlight in the presence of modified MD-TiO2,which suggests that MD-TiO2 can be used as an effective material for the removal of RRR instead of C-TiO2 and D-TiO2.

Abstract: The roles played by four major functional groups (amine, carboxyl, azo, hydroxyl groups) in the biomass of castor seeds in adsorption of seven dyes were investigated. These functional groups in castor seeds were chemically modified individually to determine their contribution to the adsorption of ionic dyes. The dyes used were remazol red B, procino yellow, fast green FCF, brilliant cresyl blue, methylene blue, neutral red, red-141. It was found that hydroxyl group inhibited the adsorption of anionic dyes but it was major functional group in the adsorption of cationic dyes, hydroxyl group was important functional group in the adsorption of all seven dyes and the effect of methylation of amino group was not significant on the adsorption of seven dyes.

Abstract:
The economic growth of the textile sector in Brazil has contributed to the generation of new jobs, qualification of the workforce and better living conditions for the population. However, due to the high activity of the sector, large volumes of toxic effluents have been generated which, if improperly disposed of, cause serious environmental damage. Therefore, alternatives in the treatment of effluents are interesting to increase the availability of this resource. A technique that has stood out, for being efficient, easy to operate and economical, is adsorption, a passive capture process where pollutants are deposited on the surface of materials. Thus, the work aimed to carry out a comparative study of the influence of pH in the removal of the dyes Remazol Black (RB), Remazol Red (RR) and Remazol Yellow (RGY) using different mixed adsorbents constituted by the fungus Aspergillus niger grown in orange peel in two different culture media. Six types of adsorbents (three for each culture medium) were produced and were treated with acid, base and without treatment. These were subjected to adsorption tests at different pHs (2, 7 and 9), using a solution (25 mg.L-1) volume of 100 mL, 0.5 g of biomass, rotation 150 rpm, 30 oC. The results showed that the adsorbents produced were able to adsorb the dyes RB, RGY, RR at different pHs. The best adsorption condition was obtained at pH 2 and the adsorbents were treated with acid, showing a promising alternative for the treatment of textile effluents.

Abstract:
Abstract The lamination process of aluminum sheets generates a flammable oil-soaked waste, which had been thermally treated (TTW) and used as adsorbent of reactive Remazol Black B (RB) and Remazol Red RB133 (RR), two of the most used dyes in the printing processes on textile industries, with reported carcinogenic and toxic properties. The adsorbent was characterized by Brunauer-Emmett-Teller (BET)-specific surface area, scanning electron microscopy and X-ray diffraction analysis. Kinetic and equilibrium studies were performed to evaluate the TTW adsorption parameters and the isotherm model which best represented the process. It was observed that the system reached the equilibrium state after 5 min for both dyes and obtained their maximum adsorption capacity (qm) at pH 4: 0.69 mg·g−1 and 2.89 mg·g−1, for RB and RR respectively; moreover, the pseudo-second-order model better fitted the adsorption kinetics. The equilibrium data were better fitted to Langmuir isotherm compared to Freundlich's for the RB and RR adsorption. The maximum removal efficiency obtained in the experiments was 80.2% for RB and 80% for RR; moreover, after the acid activation of TTW, the RB removal efficiency increased from 84.9% to 93.7%.

Abstract:
Textile effluents, when not correctly treated, cause a high impact to the environment. The synthetic dyes are used in the fibber dying process, but part of them is discarded to receiving water body. The adsorption is a technique that has been used successfully for an effective removal of color. In this work, the adsorption of reactive dye Remazol Red RB from aqueous solution using zeolite of coal ash as low cost adsorbent was studied. The zeolite was synthesized by hydrothermal treatment with NaOH solution. The effect of experimental parameters such as contact time, pH, temperature and adding salt was investigated. The kinetics studies indicated that the adsorption followed the pseudo-second-order model with correlation coefficients > 0.99. The equilibrium was reached after 360 min of contact time. The experimental data were analyzed using Langmuir and Freundlich isotherm models and the data fitted well to the Langmuir isotherm. The maximum adsorption capacity of zeolite of coal ash for Remazol Vermelho RB was 1.20 mg g-1 with adsorption efficiency between 75 and 91%. The dye adsorption was more efficient in the presence of salts.
