摘    要:采用电化学/过硫酸盐耦合体系(E-PS过程)降解水中的有机药物卡马西平(CBZ)。实验采用了分批模式进行,研究了温度、过硫酸钠浓度、初始pH值、电压等因素对E-PS过程降解CBZ的影响。反应100 min后,单独过硫酸钠、电解和E-PS过程对卡马西平的降解率分别为25.5%、59.3%、78.1%,TOC去除率分别为8.25%、23.48%、26.68%。升高温度可以有效提高CBZ的降解率。反应100 min后,在288 K,CBZ降解率为60.2%;在298 K,CBZ降解率达到78.1%;而在308 K,CBZ降解率为90.1%。CBZ的降解率随着过硫酸盐浓度的增加而提高。当过硫酸盐浓度为40 g/L时,反应100 min,CBZ降解率达94.7%。初始pH值对CBZ降解率的影响为pH 3.0 >pH 5.0 >pH 7.0;电压对CBZ降解率的影响为6 V >5 V >4 V。

关 键 词:硫酸根自由基  卡马西平  电解  过硫酸盐
