AB  - beta-Cyclodextrin-functionalized magnetic covalent organic framework 
      (Fe(3)O(4)@COF@Au-beta-CD) was developed as sorbent for magnetic solid phase 
      extraction of trace sulfonamides in meat samples prior to HPLC-MS/MS analysis. 
      The sorbent was synthesized by loading gold nanoparticles onto a Fe(3)O(4)@COF 
      surface and then functionalized by thiolated-beta-cyclodextrin immobilization via 
      Au-S bonding formation. The prepared composite material was employed for 
      sulfonamides extraction. The main parameters were optimized to obtain the best 
      extraction efficiency. The experiments of adsorption kinetics were carried out to 
      investigate the adsorption mechanism. Results showed the pseudo-second-order 
      kinetic was better fitted with the adsorption kinetics of sulfonamides. Under 
      optimized conditions, the magnetic solid phase extraction-HPLC method showed good 
      linearity (R(2) >/= 0.9936), and the limits of detection were in the range of 
      0.8-1.6 mug kg(-1). The proposed method was successfully used for quantitation of 
      sulfonamides in real samples. The recoveries ranged from 78.9 to 112.0% with 
      relative standard deviations (RSDs) < 10% (n = 5). The proposed method exhibited 
      great potential for enrichment and determination of sulfonamides in many other 
      food or environment samples. Graphical abstract.
