## Abstract A series of new chelate resins were synthesized by ringβopening polycondensation of the reaction mixture of furfural with diethanolamine, using sulfuric acid as a catalyst, and the resulting chelate resins were employed in the adsorption for metal ions Bi, In, Sn, V, Ga, Y, Ti, and Pb.
A~traet--Strong and weak resins were prepared by crosslinking branched polyethyleneimine with three dihalo-aliphatic derivatives and subsequent N-methylation. All the resins were insoluble in water and common organic solvents. It was found that the N-methylated resins showed the highest adsorption a
