| Abstract: | The extraction behavior of gold with di-(2-ethylhexyl)monothiophosphoric acid from hydrochloric acid solution has been studied. The extraction capability increases with the increase of hydrochloric acid concentration in lower concentration acid solution. It showed by continuous alternate method and saturation method, the composition of extracted species are AuR 3. IR and 1H 1 NMR studies show that the extraction mechanism of palladium is a cation exchange reaction through coordination bond P=S. |
