AB  - A novel magnetic nitrogen-doped reduced graphene oxide (Fe(3)O(4)@N-RGO) had been 
      fabricated for the first time on the basis of a simple solvothermal method and 
      then was successfully applied to extract four bisphenol endocrine disruptors 
      (bisphenol A, bisphenol B, bisphenol F and bisphenol AP) in carbonated beverages 
      coupled with high performance liquid chromatography (HPLC). The as-prepared 
      Fe(3)O(4)@N-RGO was characterized by transmission electron microscopy (TEM), 
      Brunner-Emmet-Teller (BET), X-ray diffraction (XRD), X-ray photoelectron 
      spectrometer (XPS) and vibrating sample magnetometer (VSM). The introduction of 
      nitrogen atoms not only made the wrinkle level of N-RGO increased, but also 
      retarded the irreversible aggregation of graphene sheets. Compared with 
      Fe(3)O(4)@RGO, Fe(3)O(4)@N-RGO owned larger specific surface area and more 
      adsorption sites. Hence, Fe(3)O(4)@N-RGO showed excellent extraction efficiency 
      toward bisphenol endocrine disruptors. The analytical parameters influencing the 
      extraction efficiency were optimized in detail. Under the optimal conditions, a 
      satisfactory performance was obtained. The calibration lines were linear over the 
      concentration in the range of 0.4-1000 mug L(-1) with determination coefficients 
      (r(2)) between 0.9976 and 0.9996. The limits of detection (LOD) ranged from 
      0.1 mug L(-1) to 0.2 mug L(-1). The recoveries varied from 86.52% to 101.47% with 
      relative standard deviations (RSDs) less than 8.59%. Overall, the proposed method 
      was an ef fi cient pretreatment and enrichment procedure and could be successfully 
      applied for selective extraction and determination of bisphenol endocrine 
      disruptors in complex matrices.
