摘要
本文通过加入定量的氯化亚锡和氯化碲对不同含量的Pt、Pd、Rh酸液富集共沉淀,对最后析出的Pt、Pd、Rh元素进行ICP—OES测量,确立不同含量的Pt、Pd、Rh析出率,结果表明,加入15 mL氯化亚锡和12 mL氯化碲,都可以使酸液中的100 mgPt、Pd、元素全部析出,加入15 mL氯化亚锡和12 mL氯化碲,都可以使酸液中的80 mgRh元素全部析出。
In this paper, by adding quantitative stannous chloride and tellurium chloride, the enrichment coprecipitation of Pt, Pd and Rh acid solution in different contents was carried out, and the ？nal precipitated Pt, Pd and Rh elements were measured by ICP-OES to establish precipitation rate of Pt. , Pd, and Rh with different contents. The results show that by adding 15mL of stannous chloride and 12mL of tellurium chloride, we can separate all elements of 100mgPt and Pd in the acid solution. By adding 15mL of stannous chloride and 12mL of tellurium chloride, we can precipitate all 80mg Rh elements in the acid solution.
