摘要：

An ion-imprinted polymer(HP) was prepared via surface imprinting technique under the microwave-assisted heating using Cr(III) ion as template, 3-aminopropyl trimethoxysilane as function monomer and tetraethyl orthosilicate (TEOS) as cross-linking agent. Compared with conventional method, the term of the polymerization was dramatically shortened five times by using microwave-assisted heating. The HP was characterized by scanning electron microscope(SEM), and the result shows that the size of HP is uniform and the thickness of the imprinted shell is about 40 nm. The adsorption capacity of IIP was investigated in detail. As packing material of SPE, the imprinted material was used to extract Cr(III) from urine successfully.
