AB  - In this work, magnetic nitrogen-doped porous carbon (Fe(3)O(4)@N-PC) was prepared 
      via incomplete combustion coupled with solvothermal synthesis for extraction of 
      four benzoylureas (BUs) insecticides. Among them, nitrogen-doped porous carbon 
      was produced through incomplete combustion of filter paper loaded with mixture 
      formed by Zn(NO(3))(2).6H(2)O and polyethyleneimine solution, and magnetic 
      nanoparticles were further introduced by solvothermal method. Compared with 
      magnetic porous carbon (Fe(3)O(4)@PC), the surface hydrophilicity of 
      Fe(3)O(4)@N-PC was improved by virtue of the doping of nitrogen atoms, and the 
      dispersion of Fe(3)O(4) was more uniform, which greatly exposed the adsorption 
      site. The characterization of Fe(3)O(4)@N-PC were carried out by TEM, XRD, 
      elemental analysis, XPS, BET and magnetic hysteresis curve. Besides, 
      Fe(3)O(4)@N-PC was successfully used as magnetic solid-phase extraction (MSPE) 
      adsorbent, which showed excellent enrichment factors and extraction recoveries 
      toward polar BUs insecticides due to the polar surface and introduction of 
      Lewis-basic nitrogen. The optimum amount of Fe(3)O(4)@N-PC adsorbent, extraction 
      time, pH value, desorption solvent, desorption time and PEI concentration for BUs 
      insecticides extraction were determined to be 3 mg, 10 min, 8, acetone/acetic 
      acid (19:1, V/V), 6 min and 60 g L(-1), respectively. Under this experimental 
      condition, the enrichment factors ranged from 182 to 192 with good intra- and 
      inter-day relative standard deviations (RSDs). The calibration lines were linear 
      over the concentration in the range of 1-800 mug L(-1), the limit of detection 
      (LOD) and limit of quantification (LOQ) were 0.3 mug L(-1) as well as 1 mug L(-1), 
      respectively. The recoveries for spiked sample ranged from 90.7 to 107.3% in 
      spiked Yellow River water with the RSDs less than 7.0%. The results showed that 
      the established MSPE strategy based on Fe(3)O(4)@N-PC could be used for the 
      detection of trace BUs in complex samples.
