Abstract: A method for the determination of perchlorate in drinking water by ion chromatography-hydroxide eluent was developed. An AS20 column is used for ion chromatography. The linear correlation coefficient of the standard curve is 0.999 2,the lower limit of the method is 0.005 mg/L,the accuracy is 85.7%-107%,and the precision is 1.5%-9.3%. The method is simple,stable,accurate and suitable for the detection of perchlorate in water.

Key words: ion chromatography, hydroxide eluent, perchlorate
