Abstract:

The biochemical contents of plants may vary depending on soil and climatic conditions. Under unsuitable conditions, the resistance mechanismof plants is determined by the biochemical properties of the plants. For this reason, it is of great importance to determine thebiochemical contents of some plants that are naturally grown and generally used as dye plants.

Abstract:

Heavy metal leaching limits activated carbon from sewage sludge (referred as ACS) to be used for wastewater treatment. Cr and Cd leaching from ACS exceed the permitted values. The leaching content of Cr and Cd decrease much with depositing ACS with chitosan (CS),below the permitted values. This is mainly due to the bind of Cr and Cd with the much group –NH2 of CS. The effects of initial dye concentration, pH and contact time had been studied. The dye adsorbed can act as a supple complexion agent with increasing initial dye concentration, increase the affinity for Cr and Cd. For Cd, the amount

The results indicated that the UVR absorbency of sulphur dye was not satisfactory. Generally speaking, the higher the dye concentration, the darker the shade of fabric. Nevertheless, it did not affect the UPF of fabric if the absorbency of the selected dye was ineffective.

Tests were performed at 2, 4, 6, and 24 h, with hydrogen peroxide contents varying from 1 to 5 mg/mL. Longer exposure time and a higher content of oxidant led to the degradation of methylene blue dye at up to 90%. The material can be reused

Abstract:

Polyaniline (PANI)/zinc oxide (ZnO) nanocomposites have been synthesized by in-situ polymerization of aniline monomer with ZnO nanomaterials. The PANI/ZnO nanocomposites were used as photocatalyst in the photodegradation of methylene blue dye (MB) molecules in aqueous solution. The results showed that PANI/ZnO nanocomposite greatly enhanced photocatalytic activities compared with pristine polyaniline might due to high photoexcited electronhole pairs charge separation. The photocatalytic activities of PANI/ZnO nanocomposites increased with increasing ZnO content, however, further increasing ZnO

Abstract:

Silicone reverse dyeing technology provides an important means of saving water and salts-free in the textile dyeing industry. The interactions between dyes and surfactants may influence the hydrolysis of dye during dyeing. In this investigation, the effect of ethylene oxide content in nonionic surfactant on the hydrolytic reaction of reactive dye was firstly investigated in a siloxane reverse emulsion dyeing system. Compared with no surfactants, the hydrolytic reaction of vinyl sulfone reactive dye was a slowdown when some nonionic surfactants were used during dyeing. Usually, the hydrophobic

Abstract:

Nowadays environmental pollution has become a serious problem. Textile dye waste is one of the biggest contributors to environmental pollution. Durian (Durio zibethinus) has been known as a popular fruit in Indonesia. However, only several part of the durian fruit is used, namely its flesh. Durian skin is generally only thrown away and becomes waste pollutes the environment. Durian skin waste can be used as activated carbon in overcoming textile dye waste pollution. This study aims to determine the potential of durian skin from Luwu Regency, South Sulawesi as an adsorbent for textile dye waste

Abstract: This study examines the synthesis and application of modified coconut shell (MCNS) adsorbent for the removal of Bromocresol Green Dye (BCGD) from wastewater as an alternative to cost intensive wastewater treatment techniques. The adsorbent was characterized for physicochemical properties, and also by utilizing Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectrometer (FTIR) and Energy Dispersive X-ray spectrometer (EDX). The effects of adsorbent dosage on percentage dye recovery were assessed. Isotherm data were fitted to isotherm models such as Brouers Weron Sotolo

Abstract:

In this paper, the possibility of replacing liquid electrolyte in a dye sensitized solar cells with a thin film of conductive polymer material was investigated. Liquid electrolyte in the construction of dye sensitized solar cells leaks and evaporates and leads to corrosion of the electrode, which lowers the conversion efficiency of solar radiation to electricity. The research focuses on the appropriate doping of the PVDF-HFP polymer by potassium iodide to improve its electrical conductivity and the development of thin film deposition technology for use in solar cells. Changes in PVDF-HFP surfa

Abstract:

In this paper, dye-doped polymer-dispersed liquid crystalline (DDPDLC) films were prepared with high mechanical properties and low driving voltage by doping different dichroic anthraquinone dyes. The effects of various dye and doping concentrations on microscopic morphology, electro-optical characteristics, and mechanical characteristics were investigated. The optimal doping concentrations of different dyes were also explored. The results show that the addition of all dyes decreased the contrast ratio (CR) and the transmittance and mechanical properties of the polymer-dispersed liquid crystall

Cassava leaves are leaves that can be used as a source of natural dye. Cassava leaves have a fairly high chlorophyll content and can be extracted into green dye extract. This study aimed to determine how the stability of the cassava leaf dye extract at the initial pH treatment and storage temperature and to determine the initial pH and temperature that provide the best stability to the cassava leaf dye extract during storage. This experiment used a completely randomized design with two factors. The first factor is the initial pH which consists of pH 9, pH 10 and pH 11. The second factor is the
