摘　　要：目的：建立水中亚氯酸盐及氯酸盐的离子色谱检测方法。方法：水样经处理后进行色谱柱分离，电导检测器检测，保留时间定性，峰高或峰面积定量。结果：本方法线性良好，r=0．9997，样品加标平均回收率为89．5％-105．5％，精密度高（RSD〈5％），最低检出量为0．050mg／L。结论：该方法操作简单、快速、准确、灵敏度高、干扰少，取得满意结果。Objective：To establish a method for determination of chlorate and chlorite in water by ion chromatography. Meth- ods：The water sample was separated by chromatographic column, determined by conductivity detector. Results： This method had good linearity （ r = 0. 9997 ） , the sample average recoveries rates were 89. 5 % - 105.5 % , the RSD was less than 5 % and detection limit was 0. 050 mg/L. Conclusion ：This method is simple, rapid, accurate and sensitive and has low interference.
