Kinetic studies of photoelectrocatalytic degradation of Ponceau 6R dye with ammonium persulfate

Kinetic degradation of Ponceau 6R dye using oxidation with ammonium persulfate (APS) as oxidant, and catalyzed by electro, photo, and photo-electro at pH 1.0 was investigated. Ammonium persulfate (APS) proved to be a better oxidant of dye with photoelectrocatalytic degradation (PECD). The influence of various pH of the solution on the efficiency of degradation of dye was investigated. The results were observed that the dye decolorization was enhanced using PECD at pH 2.0. The rate of degradation of dye with APS followed pseudo-first order kinetics in the dye concentration. Also, it can be seen that increasing the concentration of oxidant (APS) led to a higher rate of dye decolorization.
