PREPARATION OF SURFACE ION IMPRINTING MAGNETIC CHITOSAN NANOPARTICLES AND ADSORPTION OF Cu(Ⅱ) IONS

XIAO Ling CHEN Leying College of Resources and Environmental Sciences, Wuhan University, Wuhan 430072, China  
Surface ion imprinting magnetic chitosan nanoparticles (MGC) were prepared by binding chitosan on the surface of magnetic nanoparticles (Fe3O4), the chitosan was imprinted with Cu(II) ions and cross-linked with epichlorohydrin. The influences of anions and concentration of epichlorohydrin on effects of imprinting were investigated. Structure of MGC was characterized with transmission electron microscopy (TEM) and vibrating specimen magnetometer (VSM). The research results showed that: the mean diameter of the particles was about 25nm, saturation magnetization of MGC was 98.56emu/g, and the amount of chitosan on the MGC was 18.7%. When the initial concentration of Cu(II) ion was 3.91mmol/L, adsorption equilibrium can be reached in 15min at pH 5, the maximum adsorption capacity for Cu(II) ion was 4.07mmol/g based on the weight of chitosan, which is over 2 times of pure chitosan powder. In binary system solution containing Cd(II), Zn(II) or Pb(II) ions, the sorbent has obvious choice adsorption of Cu(II) ion compared with pure chitosan powder which almost has no selectivity. Sorbent was stable and easy recovery, the adsorption capacity was about 98% of the initial saturation adsorption capacity after being used four times.
