AB  - Cyfluthrin is a widely used pesticide. In this study, a sensitive and efficient 
      magnetic molecularly imprinted polymer (MMIP) was prepared by surface molecular 
      imprinting, which used functionalized Fe(3)O(4) particles as magnetic cores. 
      Cyfluthrin was extracted and enriched using magnetic molecularly polymer for 
      analyzing pesticide residue of Chinese herbal medicines. The crystal type, 
      microstructure, particle size, saturation magnetization, and characteristic 
      functional groups of the synthesized MMIPs were analyzed by analysis equipment. 
      The results of isothermal adsorption and kinetic adsorption indicated that MMIPs 
      reached adsorption equilibrium at 30 min, with a maximum capacity of 4.9 mg 
      g(-1), which had good adsorption performance, while selective adsorption 
      experiments showed that MMIPs had higher affinity for cyfluthrin. Under the 
      optimized conditions, the limit of detection (LOD) and the limit of 
      quantification (LOQ) were 32.987 ng ml(-1) and 109.955 ng ml(-1), respectively. 
      And linear range (30-3000ng ml(-1)) of cyfluthrin with correlation coefficient 
      R(2)=0.9979, and MMIPs were used in honeysuckle, the recoveries were 91.5% approximately 97.2%, 
      and RSD was 5.35% approximately 8.32% (n = 3). It is indicated that the magnetic molecularly 
      imprinted polymer can be used as an effective material for the specific 
      separation of cyfluthrin from honeysuckle.
