Abstract:
Azo dyes are the major group of synthetic dyes known and have given rise to many water and soil environmental problems, the most of this azo dyes were used in textile industry. The aim of this study is the removal of Disperse Blue 79 (DB 79) and Disperse Blue 165 (DB 165) as azo dyes by Hydroxyapatite (HAP). The adsorption experiments were carried out to investigate the factors that influence the dyes uptake by hydroxyapatite, such as the contact time under agitation, adsorbent dosage, initial dye concentration and size of HAP. To reduce the number of experiments, full factorial experimental d

Abstract:
Wastewater is environmentally damaged by textile industry due to dyes which are an important class of pollutants. This research explores the possibility of using the biopolymer chitosan and phosphogypsum a by-product of treating phosphate ore as adsorbents for the removal of disperse blue 165 from aqueous solution. Chitosan and Phosphogypsum were characterized by Fourier transform infrared spectroscopy and X-ray diffraction. Optimum adsorption conditions were selected by varying the adsorbent dose, solution pH, initial dye concentration, and contact time. The results show that the removal of d

Abstract:
In this study modified montmorillonite was used as an adsorbent for the removal of two selected disperse dyes i.e., Disperse Blue 56 (DB) and Disperse Red 135 (DR) from dye dispersions. The adsorption equilibrium data of dyes adsorption were investigated by using Nernst, Freundlich and Langmuir isotherm models. The adsorption kinetics was analyzed by using different models including pseudo-first-order, pseudo-second-order, Elovich and Intraparticle diffusion model. The Freundlich isotherm was found to be the most appropriate model for describing the sorption of the dyes on modified nanoclay. T

We designed and synthesized two novel blue pyrrole derivatives, 2-(3-cyano-4-(4-(dibutylamino)phenyl)-5-oxo-1,5-dihydro-2H-pyrrol-2-ylidene)malononitrile (BAPCP) and 2-(3-cyano-4-(4-(dihexylamino)phenyl)-5-oxo-1,5-dihydro-2H-pyrrol-2-ylidene)malononitrile (HAPCP), as potential candidates for use in image sensor color filters. The properties of these new compounds were evaluated, focusing on their optical and thermal characteristics in solution and color filter film forms. The molar extinction coefficient values of BAPCP and HAPCP in solution were 6.03 × 104 and 6.91 × 104 L/mol·cm. The molar e

Abstract In this research, an efficient, ecofriendly method of using coal fly ash in the form of zeolite to treat wastewater containing dyes was studied. Response surface methodology involving Box–Behnken design was applied to a batch process to evaluate the effect of process parameters such as contact time, dye concentration, agitation speed, pH, and adsorbent dosage onto zeolite. Disperse Orange 25 (DO) dye showed a maximum of 96% removal under optimal conditions of contact time of 119 min, dye concentration of 38.00 mg/L, agitation speed of 158 rpm, pH of 6.10, and adsorbent dosage of 0.67

Abstract:
The current study aimed to investigate the elimination of dyes from sewerage, using microfiltration membrane mechanism. Three dyes were applied, acid yellow-23, disperse blue -79 and acid orange -7. Experiments were performed with feed concentration (40 -120) ppm, feed flow rate (25 -65) l/h and time (0.25 -1.5) h. The membrane used ceramic membrane, constructed as a candle. It was discovered that water flow diminishes with an elevation in running time, feeding oil concentration and enhancing with elevation in the feed flow rate. In addition, it was determined that the elimination (rejection)

ABSTRACT COREXIT®9500 was used to disperse 100 barrels (bbls) of Intermediate Fuel Oil (IFO) 180 30 nautical miles south of Galveston, Texas. The dispersant was highly effective in dispersing this heavy fuel oil. Efficacy was based on the fact that only 1.5 barrels of oil washed up on the beach in the form of tarballs a week later. No reports of oiled birds or wildlife related to the incident were received. The pre-authorization limits of the Regional Response Team (RRT) Region VI On-Scene Coordinator (OSC) Pre-Approved Dispersant Use Manual were outdated; COREXIT®9500 was placed on the Nation

An electrochemical sensor has been developed using methylene blue (MB) unctionalized graphite for the selective determination of dopamine in the presence of ascorbic acid. The immobilization of methylene blue on graphite was done by carbodiimide coupling method. The methylene blue functionalized graphite was characterized by SEM, FTIR spectroscopy and UV-visible spectroscopy. The immobilization of methylene blue functionalized graphite (MB-G) on the electrode surface was made by drop casting a small volume of MB-G dispersed methanol solution on the electrode surface.

The aim of the study was to dye polyester fabric with a low molecular weight anthraquinone type disperse dye (C.I. Disperse Blue 56), with n-butylacetate as co-solvent in the microemulsion system and the presence of two bio-based auxiliaries (ortho-vanillin and coumarin), at temperatures lower than 100℃. In order to investigate the influence of temperature and auxiliaries on the kinetic dyeing process, the energy of the activation was determined by the kinetic rates constants. The activated entropy values were obtained by the theory of absolute rates of dyeing and diffusion of the activated st

The surface morphology, microstructure and element distribution of the composite were characterized by TEM, SEM, XRD, EDS respectively. The results show that the synthesized nanosized TiO2 is anatase phase with average size of 150-200 nm and can be dispersed uniformly on the surface of GACs.

Abstract:
Nonlinear refractive-index changes in GaAs are obtained at room temperature by measuring shifts of Fabry-Perot (F.P.) transmission. The 299-Å multiple-quantum-well GaAs sample was sandwiched between two dielectric mirrors (90% reflectivity) to form a F.P. etalon (finesse =10). The pump beam was tuned to 821 nm and modulated to obtain 1-μs pulses at 10 kHz. The photoluminescence from a focused pump spot at the GaAs etalon was used as a broadband probe source. Since the photoluminescence is due to carriers generated by a pump beam, the pump and probe beams automatically align themselves. The fas
