Simultaneous Determination of Alkali Metal ,Ammonium Ions and Amines by Single-Column Ion Chromatography
单柱离子色谱法同时测定碱金属、铵离子和胺类

imultaneous determination of alkali metal,ammonium ions and amines by single-column ion chromatogra-phy is described,A cation-exchange column was employed for separation with conductivity detection.Oxalicacid was used as eluent and the optimum eluent concentration was 4.0mmol/L. The detection limits,relativestandarddeviations and calibration curves for alkali metal.ammonium ions and amines were oblained. Themethod was applied for determining tap water.well water.soda water and snow with satisfactory results.
