TI  - Determination of Aflatoxin B(1) and B(2) in Vegetable Oils Using Fe(3)O(4)/rGO

AB  - In this study, magnetic graphene nanocomposite Fe(3)O(4)/rGO was synthesized by 
      facile one-pot solvothermal method. The nanocomposite was successfully used as 
      magnetic solid phase extraction (MSPE) adsorbents for the determination of 
      aflatoxins in edible vegetable oils through the pi-pi stacking interactions. MSPE 
      parameters including the amount of adsorbents, extraction and desorption time, 
      washing conditions, and the type and volume of desorption solvent were optimized. 
      Under optimal conditions, good linear relationships were achieved. Limits of 
      detection of this method were as low as 0.02 microg/kg and 0.01 microg/kg for aflatoxin 
      B(1) and B(2), respectively. Finally, the magnetic graphene nanocomposite was 
      successfully applied to aflatoxin analysis in vegetable oils. The results 
      indicated that the recoveries of the B-group aflatoxins ranged from 80.4% to 
      106.0%, whereas the relative standard deviations (RSDs) were less than 8.1%. 
      Owing to the simplicity, rapidity and efficiency, Fe(3)O(4)/rGO magnetic solid 
      phase extraction coupled with high-performance liquid chromatography fluorescence 
      with post-column photochemical derivatization (Fe(3)O(4)/rGO MSPE-HPLC-PCD-FLD) 
      is a promising analytical method for routine and accurate determination of 
      aflatoxins in lipid matrices.
