AB  - A novel type of magnetic molecularly imprinted polymers (MMIP) as the solid-phase 
      extraction sorbent was prepared, which can extract effectively the allocryptopine 
      from the waster of Macleaya cordata (Willd) R. Br. In this study, MMIP was 
      synthesized by using Fe(3) O(4) @SiO(2) , 4-vinyl-pyridine, ethylene glycol 
      dimethacrylate, and allocryptopine, and these ingredients worked as magnetic 
      core, functional monomer, cross-linker, and template, respectively. Concluded by 
      the calculation of Gaussian 09 software, different ratio models of 
      4-vinyl-pyridine and allocryptopine were simulated, and the optimal ratio was 1:5 
      and the energy was -2205.34 kJ/mol. Transmission electron microscopy, vibration 
      sample magnetometry, X-ray diffraction, Fourier transform infrared spectroscopy, 
      and thermogravimetric analysis were used to determine the morphology and 
      structure of MMIP. Furthermore, the results of adsorption experiments indicated 
      that MMIP had high selectivity, excellent recyclability, and good adsorption 
      performance (9.86 mg/g, 298 K). The adsorption process was consistent with the 
      Langmuir adsorption isotherm (R(2) > 0.98, 298 K) and pseudo-second-order 
      kinetics model (R(2) > 0.99, 298 K). After six times adsorption-desorption 
      experiments, the adsorption amount of MMIP only reduced to 8.5%. In the 
      experiments of selective adsorption, MMIP has better adsorption properties for 
      allocryptopine (ALL, C(21) H(23) NO(5) ) than those having the same functional 
      group. The limit of detection (LOD) was 0.4 mug/mL. The relative standard 
      deviation ranged from 0.09% to 0.72%. The recovery of allocryptopine in samples 
      ranged from 93.60% to 106.19%. In addition, the synthesized complex had a certain 
      adsorption effect on allocryptopine separating from the wastewater of Macleaya 
      cordata (Willd) R. Br.
