Abstract: Aseries of complexing polymeric adsorbents made of crosslinked polyamine and nickel (Ⅱ) acting as template ion were synthesized through the polycondensation of epichlorohydrin and tetraethylenepentamine in oil disperse system.The characterization of the sorption for Cu (Ⅱ),Ni(Ⅱ),Zn(Ⅱ) and Co(Ⅱ) metal ions was studied.The results show that the sorption capacities of the kinds of complexing adsorbents for Cu (Ⅱ), Ni (Ⅱ), Zn (Ⅱ), Co (Ⅱ) are 239.60, 231.30, 131.83, 81.23 mg/g resin, respectively.The sorption capacities are in following sequence: Cu(Ⅱ)≈Ni(Ⅱ)>Zn(Ⅱ)>Co(Ⅱ).
