摘　　要：提出了黄铁矿/过硫酸钠工艺并将其应用于去除水中典型抗癫痫药卡马西平,考察了黄铁矿投加量、过硫酸钠浓度、初始p H和温度对降解效果的影响。研究表明,黄铁矿能够有效地活化过硫酸钠去除卡马西平,60 min内超过95%的卡马西平被去除。最佳的黄铁矿投加量和过硫酸钠浓度分别为0.5 g/L和1 mmol/L。卡马西平的去除与溶液pH密切相关,最佳去除效果发生在pH=3.5。升高温度能够显著地提高去除效果。Pyrite/persulfate process has been proposedand used for the degradation of antiepileptic drug carbamazepine, in which the effect of pyrite dosage, persulfate concentration, initial pH and temperature on the degradation was investigated. Pyrite was found available to activate persulfate for the decomposition of carbamazepine, and more than 95% carbamazepine was removed within 60 min. The optimal pyriie dosage and persulfate concentration was 0.5 g/L and 1 mmol/L, respectively. The carbamazepine removal was pH dependent and the best carbamazepine degradation occurred at pH 3.5. Increasing temperature could significantly improve the degradation performance.
