| 摘 要： | 为了降低饮用水在氯消毒过程中产生的消毒副产物(DBPs)溴氯乙腈(BCAN)对人体带来的健康危害,采用Fe/Cu催化还原的方法降解饮用水中低浓度的BCAN,考察了BCAN的降解效果和其影响因素,探讨了其降解机制及动力学规律.结果表明,Fe/Cu具有更强的还原降解BCAN的能力,与零价铁相比,Fe/Cu(质量比为10∶1)的降解效率是其1.5倍.随着Fe/Cu投加量的增加,BCAN的去除率有明显的提高,对于初始浓度为20μg·L-1的BCAN溶液,当Fe/Cu(质量比为10∶1)投加量由5g·L-1增加到10 g·L-1,反应150 min后,去除率由51.1%增加到89.5%.BCAN降解效率随着温度的升高逐渐提高,BCAN初始浓度的变化对Fe/Cu去除BCAN的去除效果影响不大,Fe/Cu降解BCAN符合一级反应动力学规律.
