Study on Phenol Oxidation Catalyzed by Persulfate

Shen Xin Li, Wei Hu, Ying Wang, Jian Zhang Li, Cheng Duan Wang

Abstract

The phenol oxidation with persulfate catalyzed were studied. Effects of several parameters, such as dose of oxidant, pH, temperature and UV irradiation, were investigated in detail. The results showed that the phenol oxidation by persulfate could be fitted to a pseudo-first order kinetics model. The optimum acidity of the phenol oxidation system in the paper is ca. pH 8.76, the optimum temperature which is ca.70 °C and the optimum molar ratio of persulfate to the phenol is ca.40 in the solution.The results are useful for the treatment of industrial wastewater. Key words: Phenol oxidation Schiff base manganese (III) complexes Persulfate
