摘　　要：目的:本文采用梯渡淋洗离子色谱法分别测定饮用水中的亚氯酸盐、氯酸盐和溴酸盐。方法:选用IonpacAS11阴离子分析柱,0～12mmol/LKOH淋洗液,流速为1.0ml/min,电导检测器。结果:本法相关性好(r>0.9990),精密度高(RSD%<5.0),样品加标回收率为88.3%～102%,最低检出量0.008～0.010μg/ml。结论:该法操作简单、快速、准确、灵敏、适用于大批量水样分析。Objective:To develop a mehtod for simultaneous determination of chlorite, chlorate and bromate in drinking water.Methods:The method was based on IC separation under the condition of isocratic eluent with 0~12 mmol/L KOH and flow rate of 1.0 ml/min by using the IonPAC AS11 analytical column and suppressed conductivity detector.Results:This method had good relativity (r>0. 9990) and good analytic precision (RSD%<5.0). The samples′average rates of recovery were 88.3%～102% and the detection limit was 0. 008～0.010 μg/ml.Conclusion:Its advantages are simple operation, quickness, high sensitivity and precise results.This method can be applied widely and suitable for trace analysis (μg/L) of water samples.
