摘要

This study used self-made heterogeneous catalyst to investigate the degradation of benzoic acid wastewater, and the optimum conditions were obtained: Adjust the initial pH of the solution to 3, add an appropriate amount of catalyst to 1 g/L, adsorb for 210 min under magnetic stirring, then add 0.5 times the calculated theoretical amount of hydrogen peroxide (ie. 0.5Qth = 6.15 mmol/L). Finally TOC removal rate was reached of 76.76% after 90 minutes of reaction at room temperature.
