Studies on the destruction of some aqueous solutions of organic azo dyes (Brown Vopsider DMG 218) by oxidation with hydrogen peroxide associated with UV irradiation

摘要

There were done kinetic studies on the destruction of some aqueous solution of organic dyes (Brown Vopsider DMG 218) by oxidation with hydrogen peroxide associated with UV irradiation. So, there were studied the influence of stirring and UV irradiation on the decolouring degree, the influence of catalyst presence or absence. The dye destruction was appreciated through the decrease of samples colour and COD.
