Abstract

Degradation of commercial textile dye ACID RED 18 (AR18) by Photo-Fenton reagent has been investigated under irradiation of visible light in aqueous medium. The degradation process was carried out by hydroxyl free radicals which were the most reactive chemical species in the whole process. The influence of different experimental parameters such as concentration of Dye (AR18), photocatalyst (Fenton reagent), H2O2 and pH of the experimental solutions on the initial rate and photodegradation of the dye were assessed and optimized. Complete mineralization of dye AR18 (~100 %) was achieved by Photo-Fenton reagent. The photobleaching process follows first order kinetics. A simple, efficient and environmental friendly method for the photodegradation of dye is developed.
