AB  - A highly sensitive and selective molecularly imprinted (MIP) sensor combined with 
      magnetic molecularly imprinted solid phase extraction (MMISPE) was developed for 
      the determination of dibutyl phthalate (DBP) in complex matrixes. The magnetic 
      molecularly imprinted polymer (MMIP) was synthesized as solid phase extraction 
      (SPE) sorbet to extract DBP from complex matrixes and as sensing element to 
      improve the selectivity of the imprinted sensor. The morphologies of MMIP and 
      MIP-sensor were characterized by using scanning electron microscope (SEM) and 
      transmission electron microscopy (TEM). The electrochemical performances of 
      MIP-sensor were investigated by cyclic voltammetry (CV) and differential pulse 
      voltammetry (DPV). The conditions of preconcentration, elution and 
      electrochemical determination were studied in detail. Under the optimized 
      experimental conditions, the response currents of the MIP-sensor exhibited a 
      linear relationship towards DBP concentrations ranging from 1.0 x 10(-8)g/L to 
      1.0 x 10(-3)g/L. The limit of detection of the MMIP-sensor coupled with the 
      MMISPE was calculated as 0.052 ng/L. The MMIP-sensor coupled with the MMISPE was 
      applied to detect DBP in complex samples successfully.
