AB  - Most of the reported covalent organic frameworks (COFs) are hydrophobic, limiting 
      their adsorption application in sample pretreatment field. In this work, 
      sulphonate functionalized magnetic covalent organic frameworks (COFs) composites 
      were first synthesized by loading gold nanoparticles on Fe(3)O(4)@COF(TpBD) 
      surface and then functionalized by sodium 3-mercaptopropanesulphonate 
      immobilization via Au-S bonding formation (denoted as Fe(3)O(4)@COF(TpBD)@Au-MPS 
      nanocomposites), which were further utilized as adsorbents for magnetic 
      solid-phase extraction (MSPE) of fluoroquinolones. Compared with 
      Fe(3)O(4)@COF(TpBD), the composites exhibited higher affinity to 
      fluoroquinolones. Under optimized conditions, the developed MSPE method coupled 
      with HPLC-MS/MS showed good linearity (R(2) >/=0.9989) and yielded low limits of 
      detection (0.1-1.0 mug kg-(1)) for fluoroquinolones. Moreover, the proposed method 
      was successfully applied to extract fluoroquinolones from spiked meats (pork, 
      chicken and bovine). The satisfactory recoveries were in the range of 82-110.2% 
      with the relative standard deviations (RSDs) lower than 7.7%. These results 
      indicated that the Fe(3)O(4)@COF(TpBD)@Au-MPS is a promising magnetic adsorbent 
      for trace fluoroquinolones determination in meat samples. This work not only 
      provided a facile strategy for COF functionalization, but also developed an 
      efficient method for detecting fluoroquinolones in foodstuffs.
