The increasing use of synthetic dyes is alarming and their discharge as textile waste may cause substantial ecological damage. Biological decolorization of dye using microorganisms is an environmentally friendly and costcompetitive alternative to chemical methods. This study involves the application of laccase obtained from Pleurotus ostreatus, a common fungus, in decolorization and degradation...

A fast cleaving non-nucleosidic tetramethylrhodamine dye-labeled support has been developed for automated synthesis of double dye-labeled oligodeoxyribonucleotides in high yield. A mixture (1:1:2) of t-butylamine:methanol:water is used for cleavage and deprotection of dye-labeled oligodeoxyribonucleotides without any degradation or modification of dyes and nucleobases. The cleavage rate of olig...

In this research, the ability of anaerobic and aerobic biological sludges to reduce and stabilize azo dye compounds was studied. Synthetic dye solutions and an industrial textile wastewater were both treated using anaerobic and aerobic biomass, separately and in sequential step-treatment processes. The primary objective was to reduce the wastewater color to an intensity that complies with the V...

CH3NH3PbI3 perovskite nanofibers were synthesized by versatile electrospinning techniques. The synthetic CH3NH3PbI3 nanofibers were characterized by X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and photoluminescence. As counter electrodes, the synthesized nanofibers increased the performance of the dye-sensitized solar cells from 1.58 to 2.09%. This improvement w...

Introduction: Textile wastewaters from dyeing and finishing processes are heavily polluted with dyes, textile auxiliaries and chemicals and have a broad range of pH, high COD concentration and suspended particles. In this study, the efficiency of color and turbidity removal from synthetic textile wastewater samples were investigated by combined process of coagulation/ flocculation and electron ...

Blue dye (indigo) from Indigofera tinctoria leaves is a popular natural used worldwide. The lower light fastness of indigo dyes compared to that synthetic blue one the drawbacks former, limiting its utiliz
