Abstract

See full text

A preparation method of a molecularly imprinted polymer (MIP) for separation and concentration of 4-methylsterane compounds is provided. A template molecule, a functional monomer, a porogen, an initiator and a cross-linking agent are mixed and subjected to polymerization to prepare a polymer with the template molecule, which is then treated to remove the template molecule, so as to give the desired MIP. The template molecule is β-sitosterol or deoxycholic acid. The obtained molecularly imprinted polymer has multiple stable hole structures and binding sites inside, and has memory and recognition functions for the 4-methylsterane compounds, exhibiting excellent specific adsorption performance. The MIP can contribute to the accurate identification of correlation between depositional environment and maturity of crude oils or source rocks. A molecularly imprinted polymer prepared by such method, a chromatographic column and an application thereof are also provided.
