摘要： Amonolithic fiber of molecularly imprinted polymer (MIP) was prepared by in situ polymerization within the capillary with an inner diameter of 530 mu m. It was carried out in 8 min by microwave irradiation using malachite green (MG) as a template molecule, alpha-methacrylic acid (MAA) as a functional monomer, acetonitrile (ACN) as a porogenic solvent, ethylene dimethacrylate (EDMA) as a crosslinker, azodiisobutyronitrile (AIBN) as a thermal initiator. The resulted MIP fibers were pushed out from the capillary, eluted and inserted in the capillary again, which successfully used for the solid phase microextraction (SPME) procedure. The factors affecting the extraction of MG, such as the molar ratio of template/monomer (MG/MAA), concentration of NaCl, extraction and desorption time, and extraction and desorption solvents were investigated in detail. The selectivity of the MIP fibers was compared using MG analogues crystal violet (CV) and non-analogue Sudan II. It was also employed for the pretreatment of trace MG in the fish feed followed by high-performance liquid chromatography (HPLC) detection. Under the optimal conditions, the linear range of MG was 10-600 mu g/L, the detection limit (LOD) was 1.23 mu g/L and the recovery of spiked fish feed sample was 88.7 similar to 113.9%.
