Determination of six kinds of anions in drinking water by ion chromatography

To establish an analytical method for the determination of 6 kinds of anions in drinking water by ion chromatography(IC),dionex Ion Pac AS-19 anionic chromatography column was used,combined with Dionex Ion Pac AG-19 to protect column,Dionex ASRS suppressor 300 and RFC-30 automatic eluent generator.The eluent was 20 mmol/L KOH while flow rate was 1.0ml/min.Within the certain concentration range,there was a good linear relationship(r0.999),the detection limit was 1.4μg/L ~6.4μg/L,recovery range was 90.2%~106.6%.This method is simple,sensitive and accurate.It can be used as a measuring method of six kinds of anion.
