摘要
在电感耦合等离子体原子发射光谱基础上用标准加入法对纯铜中砷、铋、铁、镍、磷、铅、硫、锑、锡和锌10种杂质元素的测定进行了研究。由于工作溶液是在样品溶液中加入被测元素的标准溶液而得到，工作溶液与样品溶液具有相同基体，因此可以消除基体干扰对测定的影响。同时在测定时不需要另配制以铜打底的校准溶液，不但操作简单，而且能减少杂质元素引入，提高了方法的准确度。本法用于纯铜中杂质元素的测定，回收率为96%～108％，完全能满足纯铜样品中杂质元素的分析检测要求。
The determination of impurity elements in pure copper, including arsenic, bismuth, iron, nickel, phosphorus, lead, sulphur, antimony,tin and zinc, was studied by inductively coupled plasma atomic emission spectrometry （ICP-AES） with standard addition method. Since the working solution was prepared by adding standard solution of testing elements into sample solution, the working solution had same matrix with sample solution. Therefore, the effect of matrix interference on determination could be eliminated. At the same time, the calibration solution based on copper was not needed during determination, so the operation was simple. Moreover, the introducing of impurity elements was reduced, which improved the accuracy of method. This method was applied to the determination of impurity elements in pure copper with the recoveries of 96 % -- 108 %, which could completely meet the detection requirements of impurity elements in pure copper.
