离子色谱法同时测定大气降水中的四种阳离子

Simultaneous Determination of Four Cations in Atmospheric Precipitation by Ion Chromatography

采用离子色谱法同时分析大气降水中的四种阳离子(Na^+、K^+、Mg^2+、Ca^2+),结果显示该方法分离效果和线性良好,且方便快捷、灵敏度高、精密度好,满足大气降水中Na^+、K^+、Mg^2+、Ca^2+的分析要求。

Ion chromatography was used to simultaneously analyze four cations(Na^+、K^+、Mg^2+、Ca^2+)in atmospheric precipitation.The re⁃sults show that the method has good separation effect and linearity,and is convenient,fast,high sensitivity and good precision,meeting the analysis requirements of Na^+、K^+、Mg^2+、Ca^2+in atmospheric precipitation.
