AB  - A novel magnetic polyethyleneimine modified reduced graphene oxide 
      (Fe(3)O(4)@PEI-RGO) had been prepared and then was successfully employed to 
      extract three polar non-steroidal anti-inflammatory drugs (NSAIDs) in different 
      water matrices for the first time coupled with high performance liquid 
      chromatography-diode array detector (HPLC-DAD). The magnetic polyethyleneimine 
      (Fe(3)O(4)@PEI) composite was first synthesized via one-pot hydrothermal approach 
      and then the Fe(3)O(4)@PEI-RGO composite was fabricated on the basis of a simple 
      self-assemble approach between positive charged Fe(3)O(4)@PEI and negative 
      charged GO sheets via electrostatic interaction followed by chemical reduction of 
      GO to RGO. The as-prepared Fe(3)O(4)@PEI-RGO composite was carefully 
      characterized by transmission electron microscopy (TEM), Fourier transform 
      infrared spectrometry (FT-IR), X-ray diffraction (XRD), thermal gravimetric 
      analyzer (TGA), vibrating sample magnetometer (VSM) and zeta potential analysis. 
      As a surface modifier of RGO, PEI not just changed the polarity of RGO to some 
      extent but also offered more adsorption sites to polar NSAIDs. Compared with 
      Fe(3)O(4)@PEI, Fe(3)O(4)-RGO and Fe(3)O(4)@PEI-GO, the as-prepared 
      Fe(3)O(4)@PEI-RGO composite, which combined the advantage of PEI and RGO, showed 
      higher extraction efficiency for polar NSAIDs. In addition, the adsorption 
      mechanism was also studied. The analytical parameters influencing the extraction 
      efficiency were optimized in detail. A satisfactory performance was obtained 
      under the optimal conditions. The calibration lines were linear over the 
      concentration in the range of 1-800 mug L(-1) for all the analytes with 
      determination coefficients (r(2)) varying from 0.9972 to 0.9986. The limits of 
      detection (LODs) were 0.2 mug L(-1). The recoveries were between 91.20% and 
      101.13% with relative standard deviations (RSDs) in the range of 1.09-7.34%. 
      Overall, a fast, convenient, sensitive and eco-friendly method was successfully 
      proposed and became a promising approach for the determination of trace polar 
      NSAIDs in complex matrices.
