AB  - A new dynamic covalent polymer (DCP) gel was well designed and constructed based 
      on imine chemistry. Polycondensation of 4,4'-biphenyldicarboxaldehyde and 
      1,3,5-benzenetricarbohydrazide via Schiff-base reaction resulted in an 
      acylhydrazone bond gel (AB-gel) DCP. AB-gel DCP had three-dimensional network of 
      interconnected nanoparticles with hierarchically porous structure. AB-gel DCP was 
      successfully fabricated as a monolithic column by an in-situ chemical bonding 
      method for online enrichment and separation purpose with excellent permeability. 
      AB-gel DCP based monolithic column showed remarkable adsorption affinity towards 
      target analytes including sulfonamides (SAs) and fluorescent whitening agents 
      (FWAs) due to its strong pi-pi affinity, hydrophobic effect and hydrogen bonding 
      interaction. Then, AB-gel DCP based monolithic column was applied for online 
      separation and analysis of trace SAs and FWAs in food samples coupled with 
      high-performance liquid chromatography (HPLC). Sulfathiazole (ST) and 
      sulfadimidine (SM2) in one positive weever sample were actually found and 
      determined with concentrations of 273.8 and 286.3mug/kg, respectively. 
      2,5-Bis(5-tert-butyl-2-benzoxazolyl) thiophene (FWA184) was actually quantified 
      in one tea infusion sample with the concentration of 268.5ng/L. The spiked 
      experiments suggested the good recoveries in range of 74.5-110% for SAs in weever 
      and shrimp samples with relative standard deviations (RSDs) less than 9.7% and in 
      range of 74.0-113% for FWAs in milk and tea infusion samples with RSDs less than 
      9.0%. AB-gel DCP monolithic column was proved to be a promising sample 
      preparation medium for online separation and analysis of trace analytes in food 
      samples with complex matrices.
