PHYSICO-CHEMICAL AND ANALYTICAL STUDIES ON DEGRADATION AND QUANTITATION OF SOME ENVIRONMENTAL SAMPLES

SummaryThere are numerous types of synthetic azo-dyes of one or more azo-bonds which are widely used as chromophoric and metallochromic reagents, photochromic materials, colorants, non-linear optics, photosensitizers and sensors. Their durability, however, causeIn this Thesis, oxidation (Decolorization / degradation) of some commonly used azo-dyes was carried out by electro-generated Fenton’s reagent (Fe2+ / H2O2) using an undivided glass electrochemical cell with a reticulated vitreous carbon (RVC) cathode, a pThe studied azo-dyes were
