摘要
本文系对原工作的补充,增加一个碱熔系统,不经分离直接采用:ICP—AES法测定方铅矿和闪锌矿中钪、锡、钨、硅、钛、钒、铬、铝、锶和钡。使原有方法分析项目从23项扩大到33项。方法简便快速,数据能满足地质科研要求。
A method is developed for the determination of components including Sc, Sn, W, Si,Ti, V, Cr, AJ,Ba, and Sr in galena and sphalerite by ICP-AES.The sample is roasted to eliminate sulfur and partially As,Se,and Te. After decomposition with Na2O2, the melt is dissolved in 1:1 HNO3 containing tartaric acid to inhibit the hydrolysis of W and Sn. Y is used as internal standard to improve precision,the interferences of some elements and background are corrected by coefficients. The method proposed,together with that of the preceding paper, can be used to analyse thirty-three elements in galena and sphalerite.
