PURPOSE:To achieve the effective adsorption of Ga and to lower the equilibrium concentration of Ga, by contacting a solution containing Ga with a chelate resin having a specific structure in the molecule. CONSTITUTION:A chelate resin having the structure of formula (Ar1 and Ar2 are same or different cyclic group; M1 and M2 are thiol group, hydroxyl group, dithiocarbamic acid group or aminoalkylenephosphoric acid group; X is a molecular chain containing atom of Lewis base) is synthesized, and is made to contact with a solution containing Ga. Ga can be efficiently adsorbed and the equilibrium concentration of Ga can be lowered by this process. |
