Abstract：In the analysis for anions in environmental water with ion chromatography (IC), the drip washing liquid with 1.8 mmol/L Na2HCO3 and 1.7 mmol/L NaHCO3 is adopted. The regenerative liquid is 36 mmol/L H2SO4. The system is composed of series chromatography of PacAs-14 and conductivity detector. For 10 μL sample, within 8 min, seven kinds of anions can be detected. The working condition and the affecting factors of IC is discussed. Its relative standard deviation is between 1.9% and 6.0%, with a recovery above 97%. The method is practical, rapid and reliable. It can completely meet the demand of the analysis for anion in environmental water samples.
