摘　　要：目的:建立一种简单快速,采用直接大体积进样,电导检测饮用水中痕量溴酸盐的高效离子色谱法(HPIC).方法:选用IonPac AS19型分析柱,10～35 mmol/L 的KOH淋洗液梯度淋洗,流速为 1.0 ml/min,进样体积为 500 μl,抑制型电导检测器.结果:本法相关性好(r=0.9998),精密度高(RSD<4.0%),样品加标平均回收率在 87.2%～136.6% 之间,方法检出限为 0.68 μg/L.结论:该方法操作简单、快速、灵敏度高、重现性好.Objective：To develop a method for the determination of trace bromate in drinking water by high performance ion chromatography（HPIC） with large volumn direct injection. Methods ：The separation of the bromate was achieved on IonPac AS19 analytical column with 10 - 35 mmol/L KOH as gradient eluent and flow rate of 1.0 ml/min and injection volume of 500 μl and suppressed conductivity detector. Results ：This method had good relativity （r = 0. 9998 ） and good precision （RSD 〈4. 0% ）. The average recoveries of samples were 87.2% - 136. 6% ,the detection limit of bromate was 0. 68 μL. Conclusion ：Its advantages are simple operation, speediness, high sensitivity, good repeatability.
