Abstract: The invention belongs to the field of the analytical chemistry, and particularly relates to a 6-kinetin molecularly imprinted polymer and application thereof to a filling material for a solid-phase extraction column or a fiber coating for solid-phase microextraction. According to the invention, a novel molecularly imprinted polymer (MIP) is synthesized by using 6-kinetin (KT) as a template molecule, methacrylic acid as a functional monomer, absolute ethyl alcohol as a pore-forming agent, trimethylolpropane trimethacrylate as a cross-linking agent and azodiisobutyronitrile as an initiator and by adopting a mass polymerization method. The KT-MIP is simple to prepare, is stable in property and strong in molecular recognition capability and can be used repeatedly. The prepared MIP is used as the coating for the SPME (solid-phase micro-extraction) and the filling material for the SPE (solid-phase extraction) and can selectively extract and enrich two targets with similar structures. By combining with a liquid-phase chromatographic detecting platform, the effective separation and the high-sensitivity detection of cytokinin can be realized, and the 6-kinetin molecularly imprinted polymer is used for the analysis of substrates such as a plant sample and an environmental sample.
