离子色谱法测定酸沉降样品中的阳离子

DETERMINATION OF CATIONS IN PRECIPITATION BY ION CHROMATOGRAPHY

用新型的阳离子分离柱和抑制柱分析雨水中的阳离子（Ｎａ＋、Ｋ＋、Ｍｇ（２＋）、Ｃａ（２＋）），对这种方法的准确性和可行性进行了论证。

Cations (Na+、K+、Mg+、Ca+)in dry and wet depositions were analyzed by the new mode cation analytical column and autosuppression. The accu-racy and reliability of this methode was checked.
