Abstract

This paper attempts to explore the synergism of hybrid advanced oxidation processes, which are sono-photo-catalysis and sono-photo-activated two oxidation agents, viz. hydrogen peroxide and potassium persulfate individually using cobalt doped ferric oxide (Co-Fe2O3) as a photocatalyst, which can be excited and promote an electron to initiate the reactions. Degradation of three dye types, viz. eosin B, rhodamine B, and methylene blue have been used as a reaction model. The results revealed the binary techniques, sono-photo-catalysis to degrade eosin B and methylene blue have an antagonistic effect with negative synergy. On the contrary, rhodamine B has a positive synergy value, hence, indicating a synergistic effect. The ternary technique, which was coupling sono-photo-catalysis with the optimum amount of K2S2O8 raised the mineralization and showed a significant positive synergism effect for K2S2O8 (39.89%).
