Document Type and Number:
Japanese Patent JP6882654
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently separating a specific metal element from an acidic solution containing various metal elements by using an impregnated adsorbent having an extraction agent impregnated.SOLUTION: Provided is a method for selectively separating a specific metal element from an acidic solution, comprising the steps of: preparing an impregnated adsorbent where there is prepared an impregnated adsorbent by impregnating particles having the surface coated with a polymer with 2 or more kinds of extraction agents; and having the metal element adsorbed by the impregnated adsorbent by contacting the acidic solution containing the specific metal element with the impregnation adsorbent.SELECTED DRAWING: Figure 2
