Abstract: Four macro-porous chelate resins of Schiff base were synthesized and their adsorbabilities for seven metal ions were studied. These resins are poly-N-(3-methoxy-salicylidene) vinyl aniline (PMSVA), poly-N-(2-hydroxy-l-naphthylmethylene) vinyl aniline (PHNVA),poly-N-salicylidene vinyl aniline (PSVA) and poly-N-salicylidene vinyl benzylamine (PSB). It is shown by the experiments that the adsorption properties of the four resins for Cu2+ are satisfactory. In addition, the effects of the structures of the chelate resins on their adsorption properties for the metal ions are discussed and the adsorption rule of the resins for Cu2+ was found. On the basis of the rule, a new method for removing cu2+ selectively from the solution of electroplating nickel was drawn up by using these chelate resins and satisfactory results were obtained.
