【Abstract】 The separation and purification of rhodium from the other precious metals are one of the more difficult subjects in precious metal refining, due mainly to the complex solution chemistry of rhodium in chloride solutions. Research progresses in separating and recovering rhodium by activation-solvent extraction in recent 10 years were described. Activation treatment of a rhodium solution with some special reagents makes it labile and accelerates its reactions. Activation-extraction condition and recovery of rhodium were discussed in the absence and presence of the special reagents such as SnCl 2, SCN -, I -, Br -. The application development prospect on the activation-solvent extraction of rhodium was pointed out.更多还原
