摘要
采用抑制电导-离子色谱法,选择1.0 mL/min的流速20.00 mmol/L的KOH溶液当淋洗液,测定饮用水中溴酸根,结果表明:BrO3-的最低检出浓度为0.6μg/L,线性范围为8-40μg/L,环境标准水样平行的相对偏差为-4.0%-4.6%,相对标准偏差为7.07%,实际水样回收率范围为97.6%-102%,完全可以满足自来水中溴酸盐检测的要求,具有良好的应用价值。
An analytic method for bromate in drinking water by ion chromatography was introduced.The results showed the eluent concentration of potassium hydroxide was 20.00 mmol/ L,velocity was 1.0 mL/ min,minimum value of detectable concentration was obtained,approximately 0.6 μg/ L.The linear range was 8 - 40 μg/ L.The relative deviation of parallel environment water sample was-4.0% - 4.6% and the relative standard deviation was 7.07%.The range of recovery rate of drinking water was 97.6% - 102%.Bromate in drinking water which can meet the testing requirements,had a good application value.
