AB  - A novel magnetic solid-phase extraction (MSPE) material 
      (Fe(3)O(4)@SiO(2)-NH(2)-G2) had been prepared and employed for adsorption and 
      analysis of seven quaternary ammonium compounds (QACs) in infant fruit and 
      vegetable products coupled with high performance liquid chromatography tandem 
      mass spectrometry (HPLC-MS/MS). In this paper, Fe(3)O(4)@SiO(2)-NH(2)-G2 was 
      synthesized based on Fe(3)O(4)@SiO(2)-NH(2) and dendrimer (G2) consisting of 
      cyanuric chloride and imidazole. The morphology, configuration and magnetic 
      behavior of the magnetic material were characterized by transmission electron 
      microscopy (TEM), Fourier transform infrared spectrometry (FT-IR), X-ray 
      diffraction (XRD), and vibrating sample magnetometer (VSM). Critical parameters 
      affecting extraction efficiency, such as the adsorbent amount, sample pH, 
      extraction time, the type of eluent, and desorption time, were optimized. The 
      proposed method provided good linearity with the correlation coefficients (R(2)) 
      of 0.9992-0.9999, low limits of detection (LODs) (0.05-0.50 mug kg(-1)) and limits 
      of quantitation (LOQs) (0.20-2.00 mug kg(-1)). The satisfactory method recoveries 
      in three spiked infant fruit and vegetable products samples were between 80.12% 
      and 101.35% with the relative standard deviations (RSDs) less than 12.04%. In 
      summary, the established method was an effective sample preparation method and 
      showed good prospect for the analysis of QACs in complex matrices.
