生活饮用水中氯酸盐、亚氯酸盐和溴酸盐的离子色谱测定法

Determination of Chlorate,Chlorite and Bromate in Drinking Water by ion Chromatography

目的:利用离子色谱同时检测生活饮用水中的消毒副产物氯酸盐、亚氯酸盐和溴酸盐。方法:离子交换分离、电导检测。结果:氯酸盐、亚氯酸盐和溴酸盐的检出限分别为4.57μg·L^-1、2.18μg·L^-1、4.13μg·L^-1;相对标准偏差RSD在0.56%~0.84%;样品加标回收率在80%~120%。结论:该法能够快速准确地检测多种卤氧化物。

Objective:Determination of disinfected byproduct chlorate,chlorite and bromate in drinking water by ion chromatography at the same time.Methods:Ion exchange separation Conductive testing.Results:The determination limits of chlorate,chlorite and bromate was respectively 4.57μg·L^-1,3.18μg·L^-1,11.3μg·L^-1.The relative standard deviation was 0.56%~0.84%and the recovery was between 80%~120%.Conclusion:The method is fast,accurate and suitable for determination of the oxyhalides in drinking water.
