Pb(II)-Imprinted Polymer Prepared by Graft Copolymerization of Acrylic Acid onto Cellulose

Abstract:

Article Preview

The Pb( )-imprinted polymers were synthesized through homogeneous graft copolymerization of cellulose with acrylic acid in an homogeneous medium using Pb( ) 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( )-imprinted beads. The results demonstrated that the imprinted beads showed significantly higher imprinting efficiency than those only consisting of poly(acrylic acid) without Pb( )-imprinted, and the selectively adsorption capacity of Pb( ) on imprinted beads was higher than other competitive ions(Cu( ) or Ni( )). The imprinted beads also showed much better stability in rebinding of the imprinted ions after three adsorption-regeneration cycles.
