| 摘 要： | 本文提出将复合螯合剂（NaDDTC／8—Oxin）饱和吸附于活性碳上作为吸附材料．分离富集和ICP—AES同时测定水中痕量金属元素的方法。用ICP—AES研究了该吸附材料对某些痕量元素的吸附和解吸性能；考察了共存元素的影响。方法应用于湖水中Fe、Cu、Mn、Y和Sc的测定，检出限为ng／ml级，RSD为1．9％～4．4％，加入回收率81％～101％间，试样分析结果满意。

| Abstract: | A method for the determination on trace elements in nature water by ICP-AES with preconcentration of complexed Chelating agents (NaDDTC,Oxin)-active carbon has been presented. The adsorption and the elution conditions of trace clements have been studied. The detection limit of the method is at ng/ml level with RSD of 1. 9 %-4. 4% (n=7). The method has been applied to the determination of Se,Y,Mn,Fe,Cu in nature water with Satisfactory results. |
