摘要
Poly(acrylic acid-co-acrylamide)(PAAAM)resin was prepared from acrylic acid(AA)and acrylamide(AM)by inverse suspension polymerization.The adsorption of metal ions on PAAAM resin differed greatly at different pH values and initial concentrations.This provided a theoretical basis for the application of PAAAM resin to separate transitional metal ions Cu2+,Ni2+,Co2+.The selectivity for competitive adsorption on PAAAM resin in Cu2+,Ni2+ and Co2+ binary and ternary mixed ion solutions were investigated.It was found that there was higher selectivity on PAAAM resin for Cu2+ ions compared with other metal ions used in this study.
Poly（acrylic acid-co-acrylamide）（PAAAM） resin was prepared from acrylic acid （AA） and acrylamide （AM） by inverse suspension polymerization. The adsorption of metal ions on PAAAM resin differed greatly at different pH values and initial concentrations. This provided a theoretical basis for the application of PAAAM resin to separate transitional metal ions Cu^2＋, Ni^2＋, Co^2＋. The selectivity for competitive adsorption on PAAAM resin in Cu^2＋ , Ni^2＋ and Co^2＋ binary and ternary mixed ion solutions were investigated. It was found that there was higher selectivity on PAAAM resin for Cu^2＋ ions compared with other metal ions used in this study.
