AB  - The miniaturization of self-assembled solid phase extraction (m-SASPE) based on 
      graphene oxide/chitosan (GO/CS) coupled with liquid chromatography-ultraviolet 
      detection was developed for rapid screening of five sulfonamide residues in egg 
      and honey. GO/CS was synthesized by solution blending method and characterized by 
      FT-IR, X-ray diffraction (XRD) and scanning electron microscopy (SEM). Parameters 
      that affected extraction efficiency including sample pH, amount of the GO/CS, 
      elution solvent and rotation speed were optimized in detail. Under the optimal 
      conditions, good linear relationships between the peak area and the 
      concentrations of the analytes were obtained. The linear ranges were 
      0.01-10.00mugg(-1) with correlation coefficients (r)>==0.9989. The method detection 
      limits (MDLs) were in the range of 0.71-0.98ngg(-1). The relative standard 
      deviations (RSDs) of intra- and inter-day analysis were less than 3.5 and 7.1%, 
      respectively. The proposed method was successfully applied for the analysis of 
      sulfonamide residues in egg and honey. The average recoveries for two samples 
      spiked at levels from 0.02 to 2.0mugg(-1) were in the range of 75.3-105.2% with 
      RSDs less than 13.5%.
