A high performance liquid chromatography with magnetic zeolitic imidazolate framework (ZIF-8@Fe3O4) solid phase extraction was developed for the determination of three benzoylurea insecticides)(BUs),ie.penfluron,clofentezine and chlorfluazuron in fruit juice samples.The prepared ZIF-8@Fe3O4 sorbent was characterized by X-ray diffraction,Fourier transform infrared spectrometry,scanning electron microscopy and vibrating sample magnetometry.The extraction parameters were optimized,including pH value of solution,amount of sorbent,extraction time,eluting solvent type and volume(single elution volume×elution times).Under the optimized conditions,there were good linear relationships in the range of 2.0-200 ng/mL for penfluron and clofentezine and 3.5-350 ng/mL for chlorfluazuron,with correlation coefficients(r) of 0.999.The limits of detection(S/N=3) for three analytes were in the range of 0.6-1.0 ng/mL,and the limits of quantitation(S/N=10) were 2.0-35 ng/mL.The recoveries for all targets at three spiked levels in fruit juice samples ranged from 82.7% to 98.6%,with intra-day and inter-day relative standard deviations(RSD) of 1.2%-6.1% and 1.3%-9.0%,respectively.The enhancement factors ranged from 43.4 to 48.1 for all the analytes when 10 mL juice sample was used as loading solution.The reusability of the fabricated ZIF-8@Fe3O4 adsorbent was investigated,and the RSD for recoveries of benzoylurea insecticides for 10 consecutive adsorption-desorption cycles in sample solutions were not more than 8.8%.The proposed method is sensitive and effective,and could be applied in the determination of benzoylurea insecticides in fruit juice samples.
