摘要： 以金属Ni(Ⅱ)离子为模板,合成了高分子多乙烯多胺络合吸附剂.研究了它们对重金属离子(Cu2+,Ni2+,Zn2+,Co2+的吸附特性.结果表明,这类吸附剂对Cu(Ⅱ)、Ni(Ⅱ),Zn(Ⅱ)、Co(Ⅱ)离子的吸附容量分别达239.60、231.30、131.83、81.23mg/g(千);相应选择性顺序为Cu(Ⅱ)≈Ni(Ⅱ)>Zn(Ⅱ)>Co(Ⅱ).

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).
