| titleOfInvention | Methods for separating and recovering platinum group elements |
| abstract | PROBLEM TO BE SOLVED: To adsorb platinum group elements by adsorbing platinum group elements in an aqueous chloride solution in the presence of a high concentration of impurity elements with high selectivity and adsorption rate and higher adsorption capacity than conventional resins. The present invention provides a physically and chemically stable method for eluting group elements at a high elution rate. In a method for recovering a platinum group element from an acidic solution containing a platinum group element and an impurity element, (1) the acidic solution is converted into water having a structure in which a polymer containing an amino group is chemically bonded to a hydrophilic polymer. A first step of bringing the platinum group element into contact with an insoluble resin and adsorbing the platinum group element contained in the acidic solution to the resin; (2) washing the resin that has adsorbed the platinum group element through the first step; (3) The aqueous solution containing thiourea having a liquid temperature of 60 to 90 ° C. is brought into contact with the resin that has undergone the second step, and the platinum group element adsorbed on the resin is eluted. A platinum group element separation / recovery method characterized by sequentially passing through a third step. [Selection figure] None |
