摘要
A method for the detection of bromate and bromide in drinking water by ion chromatography-inductively coupled plasma mass spectrometry(IC-ICP-MS) was developed. The optimized conditions of IC including p H and concentration of the effluent were studied. The results showed that the above two species of bromine were baseline separated within nine minutes under the optimized conditions. The detection limits(S/N=3) of bromate and bromide were 0.23 and 0.12 μg/L, respectively. The RSD(n=6) of the peak areas was 1.2%-3.5%. The method has been successfully applied to the determination of the type bromide in drinking water samples. The recoveries were 95%-109%. The method can be used for the regular analysis of bromate and bromide in real drinking water samples.
