Process for separation and purification of platinum group metals (II) |
| abstract |
There is described a process for the separation and purification of the platinum group metals from base metal out of acidic aqueous solutions. For this purpose there is used a substituted thiourea of the formula R1R2N-CS-NH-CO-R3 or R1R2N-CS-NH-COOR3 as the precipitation agent. Preferably there are employed N,N-diaklyl-N'-benzoylthiourea wherein R1 and R2 are methyl, n-butyl, or n-hexyl. |
