摘　　要：利用超声和过硫酸钾降解水中双酚A(BPA),考察了反应条件、过硫酸钾(PS)投加量、p H值、BPA初始浓度对水中BPA降解效能的影响。结果表明,与单独超声(US)和PS氧化相比,PS/US降解水中BPA有很好的降解效果。BPA的降解率与PS投加量呈正相关,与BPA初始浓度呈负相关,降解过程符合准一级动力学(R2> 0. 98)。The persulfate(PS)/ultrasound(US)system was employed to degrade bisphenol A(BPA)in aqueous solution.The influences of reaction conditions,persulfate dosage,initial pH and concentration of BPA on the removal ratio of BPA were investigated.The results showed that the PS/US system can effectively degrade BPA in aqueous solution in comparison with PS or US system.The removal ration of BPA was positively related to persulfate dosage,and while the removal ration of BPA was negatively related to initial concentration of BPA.BPA degradation conformed to pseudo-first-order reaction kinetics(R 2>0.98)by the PS/US treatment.
