摘　　要：目的建立矿泉水中溴酸盐的离子色谱测定方法。方法选用A5-250的分析柱,用3.2 mmol/L Na2CO3+0.7mmol/L NaHCO3作淋洗液,进样体积为100μl,进行测定。结果该法线性关系良好,r=0.999 8,相对标准偏差(n=6)为1.14%,回收率为99.7%～100.3%。结论该方法分析快速,灵敏度高,重现性好。[ Objective ] To establish the determination method of bromate in mineral water by ion chromatography. [ Methods ] Analytical column of A5-250 was selected, 3. 2 mmol/L Na2CO3 ＋ 09. 7 mmol/L NaI-ICO3 as 100 μl eluent for determination. [ Results ] Good linear relationship showed in this method, r = 0.999 8. Relative standard deviation （ n = 6 ） was 1.14%. The recovery was 99. 7% - 100.3%. [ Conclusion] This method is rapid, with high sensitivity and good repeatability.
