Abstract
This paper presents the method of rhodium purification and separation from other platinum and non-precious metals. Separation of non-precious metals from rhodium acid solution was carried out using ion exchange. Process of solvent extraction was carried out to separate Pt (IV) and Pd(II) from rhodium by using TBP dissolved in petroleum ether. Platinum and palladium stripping was carried out with distillated water. Flow sheet of the process of pure rhodium winning of the 98.97% purity is presented in this paper. Obtained rhodium is convenient for usage among other purposes in electronic devices..
