微量单矿物方铅矿和闪锌矿中主体元素和痕量元素的多项分析,作者根据金属元素在阴离子交换树脂上与在盐酸、氢溴酸、硝酸、硫酸溶液之间的行为差别,试验了用阴离子交换色谱分离的条件,选用不同浓度的盐酸溶液洗提铜、钴、镍、锰、铅和银;氢溴酸溶液洗提锌;硝酸溶液洗提镉;最后用硫酸溶液洗提铋。本文所拟定的分析流程简便,试用于微量单矿物方铅矿和闪锌矿中九个元素的测定,效果较好。实验部分一、主要试剂
Based on a number of analyzes of the major and trace elements in the trace mono-mineral galena and sphalerite, the authors, based on the behavior of metal elements on anion exchange resins and in hydrochloric acid, hydrobromic acid, nitric acid and sulfuric acid solutions, The conditions for the separation by anion exchange chromatography were as follows: copper, cobalt, nickel, manganese, lead and silver were eluted by using different concentrations of hydrochloric acid solution; zinc was stripped by hydrobromic acid solution; cadmium was eluted by nitric acid solution; bismuth . The analytical procedure developed in this paper is simple and convenient, and is suitable for the determination of nine elements in trace single mineral galena and sphalerite. Experimental part First, the main reagent
