Abstract: Aseries of complexing polymeric adsorbents made of cross-linked polyamine and copper (Ⅱ) chloride, acting as template were synthesized through the condensation of epichlorohydrin and te-traethylenepentamine or ammonia in oil disperse system.Characterizations of the sorption for Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ) and Zn(Ⅱ) transition-metal ions were studied.The results show that the sorption capacity of the kinds of complexing adsorbent for Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ), Zn(Ⅱ) are 247.80, 123.40, 86.90, 153.30 mg/g respectively.The relative selectivities are in the following sequences.Cu(Ⅱ)>Zn(Ⅱ)>Ni(Ⅱ)>Co(Ⅱ).This order is relatively consistent with the natural order of its stability.
