摘要 采用亚铁离子活化H2O2/PS (过硫酸盐)降解水中的卡马西平(CBZ),对亚铁离子活化H2O2/PS降解卡马西平的影响因素进行了研究。结果表明,n(H2O2)/n(PS)为3∶1、Fe2+的浓度为0.1 mmol/L、pH=3、反应时间为30 min时,卡马西平的降解率达到62.9%。增加Fe2+的浓度能提高卡马西平的降解效率,增加卡马西平的初始浓度会降低卡马西平的去除率,但提高了卡马西平总的去除量。通过甲醇和叔丁醇淬灭实验验证了在亚铁离子活化H2O2/PS体系中HO·是主要的反应自由基。该研究为降解水中卡马西平提供了一种技术支持。

Abstract: Carbamazepine is degraded by ferrous ion activated hydrogen peroxide and persulfate (Fe2+-activated H2O2/PS) and the influencing factors are studied.It is shown that the degradation rate of carbamazepine can reach 62.9% in 30 minutes when n(H2O2)/n(PS) is 3:1,Fe2+ dosage is 0.1 mmol·L-1 and the appropriate pH values is 3.Increasing Fe2+ dosage can improve the degradation efficiency of carbamazepine.Increasing the initial concentration of carbamazepine will reduce the removal rate of carbamazepine but can enhance its total removal amount.Besides,hydroxyl radicals are proven to be the predominant active species in the Fe2+-activated H2O2/PS system by using methanol and tertiary butanol as scavengers.This research provides a type of technology reference for the treatment of carbamazepine.
