摘要: Using nickel(Ⅱ) acetate-2,2′-dipyridyl complex as template and N-vinyl-2-pyrrolidone
(NVP) as coor-dinate functional monomer, a new kind of metal-complexing template
molecularly imprinted polymer (MIP) was prepared. The results of equilibrium binding
experiments in aqueous solution showed that the MIP had higher bind-ing capacity for
nickel(Ⅱ)-2,2′-dipyridyl than the non-imprinted polymer with the same chemical
composition. The influences of metal ions and pH of solution on the recognition performance
of MIP were investigated. The binding characteristics of MIP were evaluated by the
Scatchard analysis with one-site and two-site binding equations, re-spectively. The results
on substrate selectivity of imprinted polymer revealed that MIP had better binding affinity
for template among the tested compounds.
