AB  - A novel mesoporous ZrO2 immobilized magnetic Fe3O4 microsphere (m-ZrO2@Fe3O4) was 
      successfully synthesized and characterized by transmission electron microscope 
      (TEM), X-ray diffractometer (XRD), nitrogen adsorption measurement (NAM), 
      energy-dispersive X-ray analysis (EDX), vibrating sample magnetometer (VSM). Then 
      the resultant m-ZrO2@Fe3O4 and an n-octadecylphosphonic acid modified magnetic 
      microsphere (Fe3O4-OPA) were employed as clean-up co-adsorbents of QuEChERS 
      (Quick, Easy, Cheap, Effective, Rugged, Safe) method for the analysis of 42 
      pesticides and 7 polychlorinated biphenyls (PCBs) in fish samples. Lipid 
      co-extractives such as fatty acids in QuEChERS extracts could be efficiently 
      removed through the Lewis acid-Lewis base interaction between m-ZrO2@Fe3O4 and 
      carboxylic groups, while some other apolar interferents could be adsorbed through 
      hydrophobic interaction by Fe3O4-OPA. Meanwhile, the magnetic property of 
      adsorbents endows the clean-up procedure with manipulative convenience. Several 
      parameters affecting the clean-up performance were investigated. Under the 
      optimal conditions, the modified QuEChERS method combined with gas 
      chromatography-tandem mass spectrometry (GC-MS/MS) for the multi-class, 
      multi-residue analysis of pesticides and PCBs in fish samples was validated 
      according to linearility, recovery and precision. Good linearities were obtained 
      for all analytes with R(2) larger than 0.9903. Limits of detection (LODs) were 
      found to be in the range of 0.02-4.40 ng/g. The method recoveries of all analytes 
      spiked at three concentration levels in blank fish samples were from 69.8% to 
      117.1%, with the intra-day and inter-day relative standard deviations (RSDs) less 
      than 13.4% and 16.5%, respectively.
