ICP-AES法测定进口铜精矿中有害元素

研究了ICP-AES法测定进口铜精矿中铅、锌、钴、镍、镁、镉、砷、锑、铋、汞的含量，采用测定标样、加标回收试验，并与AAS方法比较和参加全国水平测试等多种方法对该方法进行考察，证明该方法准确可靠、简便快速，可用于进口铜精矿的快速检验。

ICP-AES ANALYSIS OF SOME IMPORTED COPPER CONCENTRATES

ICP-AES was applied to the analysis of some imported copper concentrates and the optimum conditions for the determination of 10 elements (Pb Zn Co Ni Mg Cd As Sb Bi Hg) in the samples were studied. Separate experiments were carried out to test for the recovery and precision of the proposed method, and the accuracy and feasibility of the method were further tested by checking with standard samples and by parallel analysis with AAS. Consistent results were obtained. The proposed method was also used as one of the selected methods in the interlaboratory comparative testing of analysis of copper concentrates among 32 analytical laboratories, and the results obtained by this method were in good conformity with the median values. It was proved that this method is accurate, precise, easy and rapid to be used in routine analysis.
