采用ICP-AES法对降水中的钾钙钠镁金属离子进行了测定,结果表明：各元素线性相关性均大于0.9990,加标回收率为94.4%～102.6%,相对标准偏差为0.41%～3.05%之间,均可满足要求。相比于火焰原子吸收分光光度法,该方法具有前处理简单,干扰少,测定准确、快速等特点。

A method for the simultaneous determination of potassium （K）, calcium（Ca）, sodium （Na）, and magnesium （Mg） in rainfall by ICP -AES was presented. The detection limits, accuracy and precision test were carried out. The results showed the linear correlative coefficient were higher than 0.9990, the recoveries were in the range of 94.4% 102.6% and the relative standard deviation（RSD） values were 0.41% -3.05%, and all can meet the requirements. Compared to the atomic absorption spectrometry （ AAS）, the method had the advantages of simple sample preparation, less interference and fast, accurate and simultaneous multi -element analysis.
