| 摘 要： | 研究了利用热激活过硫酸钠降解卡马西平和奥卡西平复合污染的规律.通过HPLC分析发现,在30～ 50℃时,卡马西平和奥卡西平的降解率随着温度的升高而升高,50℃时,反应90 min后卡马西平降解率为65.5％,30 min内几乎能完全降解奥卡西平;提高过硫酸钠浓度有利于卡马西平和奥卡西平的降解,当过硫酸钠浓度为12.0 mmo1.L-1时,可分别在90 min和20 min内几乎完全降解卡马西平和奥卡西平;升高pH能提高卡马西平和奥卡西平的降解率,当pH为9.0时,可分别在75 min和15 min内将卡马西平和奥卡西平几乎完全降解.经淬灭实验和电子顺磁共振波谱仪检测表明,热激活过硫酸钠降解卡马西平和奥卡西平体系中起主要作用的自由基是·OH.结果表明,该法操作简单,pH适用范围广,可以在短时间内高效降解卡马西平和奥卡西平,实际应用前景良好,并可为实际废水中卡马西平、奥卡西平或其他有机污染物的降解提供参考.
