| description | PROBLEM TO BE SOLVED: To provide a method for separating and recovering platinum group elements capable, while preserving a performance of adsorbing, selectively at a high adsorption ratio in the co-presence of high-concentration impurity elements, platinum group elements within an aqueous chloride solution, of eluting, at a high elution ratio, adsorbed platinum group elements.SOLUTION: The provided method for separating and recovering platinum group elements is a method for separating and recovering platinum group elements from an acidic solution including platinum group elements and impurity elements wherein the following steps are executed in proper order: a first step of inducing, by contacting the acidic solution with a resin consisting of a water-insoluble polymer alloy constituted by an amino group-containing polymer and a polymer other than amines, the adsorption, onto the resin, of platinum group elements included within the acidic solution; a second step of washing the post-adsorption resin; and a third step of inducing the elution of the platinum group elements from the resin thus washed. |
