英文摘要	In this paper, a simple but efficient method for the extraction and analysis of bifenthrin in water samples was proposed. The Fe3O4-based nanocomposites ( Fe3O4@ m-SiO2/ PSA@ Zr-MOF) were successfully synthesized and developed as adsorbents for magnetic solidphase extraction. With the solvothermal reaction and solgel method, the resultant adsorbents exhibited excellent characteristics of large surface areas, homogeneous pore size, strong magnetic responsivity and high hydrophilic-ity. The parameters affecting the extraction performance including adsorbent amounts, adsorption time, species of eluents and desorption time were investigated. Under the optimal conditions, validation experiments such as recovery, reproducibility and limits of detection ( LOD) were carried out and showed satisfactory results. The LOD of the targeted analytes was found to be 0.5 mu g L-1. The average recovery was 103.2% with the intra-day and inter-day relative standard deviations of 2.0 and 3.5%, respectively. Ultimately, the novel magnetic adsorbents were successfully applied to detect the bifenthrin compound in real water samples.; Key Laboratory of Cigarette Smoke, Technology Center of Shanghai Tobacco (Group) Corp; Natural Science Foundation of China [41322024]; SCI(E); ARTICLE; 3; 463-471; 80
