Degradation of phenol in water by Fe(II)-citrate activated persulfate oxidation

Maoying Fang, Mengqian Mao, Zhiguo Wen

Abstract

Abstract To enhance the degradation efficiency, complexing agent citric acid (CA) and trisodium citrate (TC) were introduced into the Fe(II)-persulfate (Fe2+/PS) oxidation system to degrade phenol. And the optimal operating conditions were determined. The results showed that Fe2+-citrate/PS system had higher degradation efficiency than the others. The optimal operating conditions to degrade phenol in water were: a PS concentration of 0.06 mol/L, a Fe2+ concentration of 0.02 mol/L and a TC concentration of 0.01 mol/L, while reaction temperature and the initial pH values had little influence on the phenol degradation.
