| Abstract: | 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 . |
