| Abstract: | This paper sets up a new method to analyse anions in acid rain by ion chromatography method.The chromatography conditions were as IonPac AS18 anion exchange column and 38 mmol/L KOH isocratic eluent which was generated by automatic eluent generator.The determination was processed by suppressed conductivity digital detector. The results have beautiful reproducibility,selectivity,sensitivity.Also this method can give good linear range and spiked recoveries. |
