摘要
本文提出了一个浮选Rh(Ⅲ)水合阳离子的新方法。首先将Rh(Ⅲ)转化为水合阳离子,然后以十二烷基苯磺酸钠浮选,与仍处于氯络阴离子状态的Pd(Ⅱ),Pt(Ⅳ)分离,研究了影响浮选分离的各种因素。本文还考察了经水解、酸化预处理后,阳离子表面活性剂浮选PdCl_4^(2-)、PtCl_6^(2-)与Rh(Ⅲ)水合阳离子分离的效果。
A new flotation method of aqueous Rh (Ⅲ) cation has been developed. After hydrolysis and acidification, rhodium (Ⅲ) turned to aqua-cation of Rh(Ⅲ) which was then flotated by SDBS. In this way, Rh(Ⅲ) was separated from Pd(Ⅱ) (PdCl_4^(2-)) and Pt(Ⅳ) (PtCl_6^(2-)). Factois influencing flotation and separation, and the flotation and separation of PdCl_4^(2-) and PtCl_6^(2-) from Rh(Ⅲ) by cation surfactants have also been studied.
