| titleOfInvention | Method for recovery of Ir from platinum group-containing solution |
| abstract | The invention provides a method for recovery of Ir from a platinum group-containing solution. The method raises an adsorption rate of activated carbon by Ir and can recover Ir more effectively. The process of recovering Ir from platinum a group-containing solution comprises the following steps of: a neutralization process: adding a neutralizer for depositing vitriol in an acid solution including Ir to deposit and separate sulphate ions in the acid solution and to make free acid concentration of the acid solution be 0.03 mol/L-1.2 mol/L and to reduce ion strength in the acid solution; a vulcanization process: adding a vulcanizer to remove at least one impurity selected from the group of As, Cu, Fe, Ni, Zn, Bi, Pb, Te, Sn and Sb included in the acid solution including Ir; and an activated carbon adsorption process: passing the neutralized acid solution including Ir in activated carbon to make Ir absorb the activated carbon. |
