Abstract: Objective:To prepare triadimenol molecularly imprinted polymer,and establish a method for determination of triadimenol residues in food.Methods:Molecularly imprinted polymer(MIP) was prepared by the way of bulk polymerization,using triadimenol as template molecule,methacrylate acid(MAA) as functional monomer,ethylene glycol dimethacrylate(EDMA) as crosslinker.MIP was used as solid phase extraction agent to treat samples.Triadimenol residues in the samples were determined by high performance liquid chromatography.Samples were analyzed on Shim VP-C18(150 mm4.6 mm,5 m)column,the mobile phase consisted of methanol-water(40: 60,v/v),the wavelength was 224 nm.Results:The results showed that the linear range of triadimenol was 0.1-200 μgmL-1,linear correlation coefficient was 0.9998;the detection limit was 0.5 μgg-1;under 2 μgg-1 and 10 μgg-1 added levels,the average recoveries were between 79.3%-86.0%,and the relative standard deviations(RSDs) were =2.3%(n=5).Conclusion:This method has good sensitivity and reproducibility,is an effective method of detecting triadimenol fungicide residues in food.
