摘要
采用积分安培-离子色谱法同时测定地下水中的溴离子和碘离子，该方法的相关性好（ r＞0．999），精密度高（RSD％＜4．0），样品加标回收率为90～110％，溴离子检出限为5．6μg/L ，碘离子检出限为2．1μg/L。本法简便、快速、准确且选择性好，可用于分析地下水中的溴离子和碘离子。
A method for determination of bromine and iodine ions in groundwater by ion chromatogra-phy with integrated amperometric detector was studied in this paper .It has good relativity （r〉0 .999） and high precision （RSD% 〈4 .0） .The average recoveries of samples were 90% -110% ,the detection limit of bromine ion was 5 .6μg/L and iodine ion was 2 .1μg/L .This method is simple ,rapid ,exact and has good selectivity ,being suitable for detection of bromine and iodine ions in groundwater .
