摘要
本文对使用ICP-AES法测定水中含有的钠、钾、钙、镁、铝、钡、铜、钴、铁、锰、钼、铬、镍、硅等元素进行了研究,该方法可获得良好的灵敏度,对多元素含量的测量速度快,回收率为96%-103.4%,标准曲线相关系数大于0.9998,相对标准偏差小于5.0%,测定检测限低,能够满足分析的需要。
The determination of some elements including Na, K, Ca, Mg, Al, Ba ,Cu,Co,Fe, Mn, Mo, Cr, Ni, Si in water by means of ICP-AES was studied. It indicated that such technology method might provide with an excellent sensitivity. It was very easy and fast for the simultaneous determination of multi-elements. The recoveries of elemonts were 96% - 103.4% ,and the linear correlation might be up to 0.9998. The relatively standard deviation was found to be less than 5.0%. It could mcet the demands for analysis.
