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 an atomic group of a specific formula in the molecule. CONSTITUTION:A chelate resin having an atomic group containing two or more N atoms and represented by the formula (n is integer of 2-10) (e.g. 2-10C polyethylene-polyamino group, guanidine group, amidino group, hydrazi group, hydrazino group, hydrazono group, azo group) in the molecule 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. |
