| Abstract: | In the analysis for anions in environmental water with ion chromatog raphy (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 rel iable.It can completely meet the demand of the analysis for anion in environment al water samples. |
