Title
Decolourisation effects of Vat Green 01 textile dye and textile wastewater using H2O2/UV process
Abstract

Wastewaters from textile industry contain various pollutants including a high content of organic matter, surfactants, additives and dyes. Dyes have obtained notoriety as hazardous substances, because most of them are toxic and considered to be resistant to biodegradation. Recently, advanced oxidation processes (AOP) have received considerable attention because it is possible to degrade organic compounds and colour from wastewaters. The decolourisation of Vat Green 01 textile dyestuff and real textile wastewater was investigated using UV radiation in the presence of H2O2 as function of pH, hydrogen peroxide concentration and dye concentration (in the study with the dyestuff). The results showed that the degradation increases as the initial H2O2 concentration increased up to a certain point at which hydrogen peroxide inhibited the wastewater photolytic degradation. The decolourisation rate follows pseudo-first order kinetic with the respect to the dye concentration.
