AB  - A molecularly imprinted polymer (MIP) base on the surface of graphite oxide (GO) 
      has been developed for the selective recognition of di(2-ethylhexyl)phthalate 
      (DEHP), and applied for the extraction of DEHP in a milk bag sample, with 
      detection by high-performance liquid chromatography. The surface-molecularly 
      imprinted material was prepared by precipitation polymerization in 
      N,N-dimethylformamide (DMF) solvent, using GO as the supporting material, DEHP as 
      the template molecule, and methacrylic acid (MAA) as the functional monomer; the 
      synthesis conditions were also optimized. The obtained GO-MAA-MIP was 
      characterized by Fourier transform infrared (FTIR) spectroscopy and transmission 
      electron microscopy (TEM). The adsorption properties of the product were 
      evaluated by adsorption experiments, including adsorption isotherms, kinetics, 
      selectivity, saturated adsorption capacity, adsorption equilibrium time, and 
      reusability. Under optimized conditions, DEHP was effectively extracted in the 
      real sample (milk bag) and detected by HPLC. Linearity was obtained with a 
      correlation coefficient (R(2)) of 0.9979 in a linear range of 0.5-50 mg/L. The 
      limits of detection and quantitation were 0.03 mg/L and 0.1 mg/L, respectively. 
      The average recoveries of the spiked samples at three concentration levels of 
      DEHP ranged from 81.6% to 92.4% with relative standard deviations (RSDs) less 
      than 7%. The results indicated that the proposed GO-MAA-MIP-SPE (solid phase 
      extraction) protocol with HPLC-UV detection could be applied for the selective 
      analysis of DEHP in real samples.
