| Abstract: | A systematic study was performed on the extraction and separation of cadmium from iron halides in pure halo-acid solutions and their mixtures with H2SO4 and H3PO4. As solvents Amberlite LA-2, TBP, nitrobenzene and HDEHP were used. Recommended separation media for the amine are 2M HCl, 1M HBr, 1.12M HCl?2M H2SO4, 0.64M HBr?2M H2SO4, 1.12M HCl?4M H3PO4 0.64M HBr?7M H3PO4 and for TBP the medium 0.64M HBr?4M H3PO4 is the only suitable condition. |
