decolorization of synthetic blue dye solution by advanced oxidation process AOP

In this study, we used advanced oxidation process (Fenton, Fenton-like and ammonium per sulfate (APS) methods) for the removal of a cationic and anionic blue dyes, the Basic Blue 3 (BB3) and Acid blue 62(AB62), from aqueous solutions. AOPs reactions are mixture of H2O2 or ammonium per sulfate as a oxidizing reagents with metal catalysts. The formed hydroxyl radicals and sulphate radical anion led to the oxidative degradation of BB3 & AB62. The results show that the optimum amounts of Fenton and Fenton -like reagent was 5.6 mg/ L as a metal catalyst ion and 1 g/L of H2O2, In (APS) reactions 50 mM of ammonium per sulfate concentration for an initial dye concentration at 50 mg/L were used.In these reactions, It was found that the re moval of dye was enhanced using pH 3.0. The best reagent for AB62 dye was FeCl2.4H2O and for BB3 dye was NH4Fe(SO4)2 .%Removal of AB62&BB3 were up to ٪99.9.
