| Abstract: |
| The molecular imprint is a novel technique prepared functionalized materials for molecular recognition and is developing in recent years. The advantages of imprinted polymer and ionic imprinted polymer prepared using molecular imprinting technique are: highly predetermined selectivity, molecular recognition capability and good practicality. Combining with solid-phase microextraction method, imprinting techniques have wide application perspectives in selective separation and preconcentraction of trace constituents in samples. In this paper, the recent developments on applications of molecular imprinting techniques in selective separation and preconcentration of trace metals were introduced. The preparation of a series of the ion-imprinted polymers, which contain one of the ions as Hg(II)-,Ni(II)-,Cu(II)-,Co(II)-,Zn(II)- Pb(II)-, UO22＋-,and MBT-,DBT-,TBT-, as well as phenyl tin, were described and the applications of these ion-imprinted polymers in analysis of environmental, food, biological, medical as well as drug samples were demonstrated in detail. |
