用IRIS/AP-ICP-AES法对大气降水中K、Na、Ca、Mg同时测定的研究

本文采用ＩＣＰ－ＡＥＳ法同时测定降水中Ｋ、Ｎａ、Ｃａ、Ｍｇ的含量。根据各元素的特性，为选择合适的入射功率、雾化压力、提升量以及试样的酸度等条件进行了探索，并且，用选定的最佳条件对样品进行测试。方法简便、快速、准确。测试结果的相对标准偏差均小于３％。

Study on Simultaneous Determination of K,Na,Ca and Mg in Rainfall by IRIS/AP-ICP-AES

This paper,the contents of K,Na,Ca and Mg in rainfall are determined simultaneously by ICP AES.By elements characteristic,studies a series of parameter conditions,such as RF power level,nebulizer pressure,elevating quantity,acidity and so on,the optimum condition for analysis is selected,and the samples are analyzed by the condition.This method is simple,rapid and accurate.The relative standard deviations of determined results of K,Na,Ca and Mg are less than 3%.
