PURPOSE:The titled resin capable of selectively adsorbing and recovering valuable metals even from a solution containing a large quantity of Al<3+> ions, having 2-methyl-8-hydroquinone as a ligand. CONSTITUTION:A chelate group-containing phenolic resin containing 2-methyl-8- hydroxyquinoline as the chelate group shows excellent complexing and separating abilities for metal ions and can adsorb metals, for example, Ga, Mo, and In, even from a solution containing a large quantity of Al<3+> ions. This resin can be obtained by reacting 2-methyl-8-hydroxyquinoline with an aldehyde under an alkaline condition to obtain an initial product, and either reacting the initial product with a phenol and an aldehyde to convert it into a three-dimensional structure by crosslinking, or by reacting the initial product with a phenol, an aldehyde and an aliphatic polyamine to convert it into a three-dimensional structure by crosslinking. |
