离子色谱法测定瓶装矿泉水中痕量溴酸盐
Determination of Trace Level Bromate in Bottled Mineral Water by Ion Chromatography
摘要
Abstract
A new method was developed for determination of trace level bromate in drinking water by ion chromatography with large volume direct injection and without pretreatment.The separation of bromate was achieved by IonPac AS23 anion exchange column and a carbonate/bicarbonate buffer solution was selected.The detection limit of bromate was decreased to 0.2μg/L, linear coefficient is 0.9999, RSD of the peak area for the standard solution of five different concentration was below 10%.The method was applied to the detection of bromate in Beijing's bottled drinking water.The recoveries of spiked standard were 98%~ 106%.The detection values were 1 .78~14.49μg/L.关键词
