AB  - A novel mosaic structure Silica@C/Co@ZIF-67 composite was synthesized by 
      successfully embedding Co nanoparticles on the surface of silica spheres with the 
      help of thermoplastic polyethyleneimine by carbon-reduction. The ZIF-67 
      half-shell layer structure was synthesized by the in-situ growth of ZIF-67 on the 
      surface of silica spheres through the coordination of 2-methylimidazole with Co 
      metal nodes. The composite was used as a magnetic solid-phase extraction 
      adsorbent combined with high performance liquid chromatography-ultraviolet 
      detector (HPLC-UV) for the extraction and determination of benzoylurea 
      insecticides (BUs) in vegetables and tea. Based on the presence of pi-pi, 
      hydrophobic and hydrogen bonding interactions between Silica@C/Co@ZIF-67 and BUs, 
      the BUs were rapidly captured by the composites resulting in high adsorption 
      performance. Under the optimal extraction parameters, the linear ranges were 
      0.3-200 microg L(-1) for diflubenzuron, 0.6-200 microg L(-1) for chlorbenzuron, and 
      1.0-200 microg L(-1) for triflumuron, teflubenzuron, and flufenoxuron, with 
      correlation coefficients (R(2)) greater than 0.9991. The limits of detection 
      (LODs) of the method were 0.1-0.3 mug L(-1), and the relative standard deviations 
      (RSDs) were 1.2-3.0% for intra-day and 2.6-4.6% for inter-day. In the spiked 
      recovery experiments of vegetables and tea, the recoveries of the five kinds of 
      BUs ranged from 75.8 to 112.9%. In addition, after 10 repetitions using 
      Silica@C/Co@ZIF-67, the recoveries of the five kinds of BUs were still as high as 
      78.4 to 83.9%.
