Introduction: Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, teratogenic, and non- biodegradable. Carcinogenic and mutagenic potential of some azo dyes as a category of common dyes in different types of industries has been reported. Reactive red 198 is one of the azo dyes that are currently used in the text...
Decolourization activity of Phanerochaete chrysosporium for three synthetic dyes viz., congo red, malachite green and crystal violet and impact of additional carbon and nitrogen supply on decolourization capacity of fungus were investigated. Maximum decolourizing capacity was observed up to 15 ppm. Addition of urea as nitrogen source and glucose as carbon source significantly enhanced decolouri...
An efficient synthetic protocol to functionalize the cyanoacrylic acid anchoring group of commercially available MK-2 dye with a highly water-stable hydroxamate anchoring group is described. Extensive characterization of this hydroxamate-modified dye (MK-2HA) reveals that the modification does not affect its favorable optoelectronic properties. Dye-sensitized solar cells (DSSCs) prepared with t...
In this paper, extract of papaya leaves are used as a natural dye and combined by variations of solvent concentration applied on DSSC (Dye-Sensitized Solar Cell). Indonesian geographic located on the equator line occasions the magnitude of the potential to develop organic solar cells made from extracts of chlorophyll as a substitute for inorganic materials or synthetic dye on DSSC material. Dye...
Decolorization of synthetic azo dye solution of Congo red dye, as an anionic dye was studied in a batch reactor using Advanced Oxidation Process (AOP). Congo red has been selected amongst azo dyes due to its high solubility in aquatic environment. AOP is effectively removing color in azo dye wastewater due to its strong oxidizing property by breaking down the functional group that impacting col...
