| 摘 要： | 采用电感耦合等离子体原子发射光谱法(ICP-AES)进行方铅矿中多元素同时测定.通过对方铅矿样品化学处理试验建立了HCl-NH4Cl-HNO3的溶矿体系.本体系采用基体匹配、背景系数和元素干扰系数校正及元素内标法确定了最佳综合实验测试条件.本实验建立的ICP-AES法同时测定方铅矿中镉、钴、铜、铁、铟、铅、锌7种元素的方法,本方法测量相对误差RE (n=8)为1.50%～7.50%,相对标准偏差RSD (n=8)为1.7%～5.7%.经国家一级标准物质GBW 07269分析验证可以满足方铅矿单矿物样品的分析要求. |

| Abstract: | A method for simultaneous determination of multi elements in galena by inductively coupled plasma atomic emission spectrometry(ICP-AES) was studied.The system of HCl-NH4Cl-HNO3 dissolving ore was set up by chemical treatment for galena samples.The optimal experimental conditions were obtained by matrix element match,background coefficient and element interference coefficient correction as well as element internal standard method.The method of simultaneous determination of seven elements in galena such as cadmium,cobalt,copper,iron,indium, lead and zinc by inductively coupled plasma atomic emission spectrometry was established.The relative errors RE(n=8) are between 1.5% and 7.5%,and relative standard deviations RSD(n=8) are between 1.7% and 5.7%.The method can satisfy demand for galena analysis of single mineral sample through analysis verification for national first level standard material(GBW 07269). |
