Abstract: The Pb(II)-imprinted polymers were synthesized through homogeneous graft copolymerization of cellulose with acrylic acid in an homogeneous medium using Pb(II) as template. The prepared copolymers were characterized by FTIR and SEM. The batch adsorption experiments were conducted to evaluate the adsorption capacity of the Pb(II)-imprinted beads. The results demonstrated that the imprinted beads showed significantly higher imprinting efficiency than those only consisting of poly(acrylic acid) without Pb(II)-imprinted, and the selectively adsorption capacity of Pb(II) on imprinted beads was higher than other competitive ions(Cu(II) or Ni(II)). The imprinted beads also showed much better stability in rebinding of the imprinted ions after three adsorption-regeneration cycles.
