Abstract
An analytical method for the simultaneous determination of bromate, chlorite, chlorate and common inorganic anions in drinking water was developed using large-volume direct injection and chemically suppressed ion chromatography （IC）. An IonPac AS9-HC separation column and an IonPac AG9-HC protection column were used. The mobile phase was 12 mmol/L Na2CO3 at a flow rate of 1.0 mL/min. The injection volume was 100 t.tL. Ten anions could be detected by the method within 18 rain with average spike recovery of 93.0%- 103.1% （n = 5）. The correlation coefficients of calibration curve were 0.9993- 0.9999. This method was sensitive, accurate and rapid. It has been applied to determine Kunming tap water and a variety of commercial drinking water with satisfying results.关键词
