Open publisher page 0 citations

Abstract

The present paper developed a method in which we used a brand new high capacity high efficiency ion exchange column which were brought by large volume injections and suppressed conductivity detector to analyse trace bromate in drinking water matrix.The separation of bromate and other anions were obtained by IonPac AS23 anion exchange column which is a carbonate/hydroxide double selectivity column and a carbonate/bicarbonate buffer solution was selected.This method whose method detection limit is 0.225 μg·l~(-1),linear coefficient is 0.9999,RSDs are from 1.151% to 7.872% and recoveries are between 97.6%—111.1%.
