PG  - 342-7
AB  - A magnetic carbon nanotube hybrid material was prepared using a chemical 
      co-precipitation method. The Fe3O4 nanoparticles were enclosed onto the surface 
      of the acid multi-walled carbon nanotubes (AMWNTs), and they were identified as 
      Fe3O4/AMWNTs composites. This hybrid materials displayed typical 
      superparamagnetic behavior, good dispersibility, and good adsorption capacity for 
      pyrethroid pesticides. A magnetic solid-phase microextraction (MSPE) procedure 
      based on Fe3O4/AMWNTs composites, combined with gas chromatography, was developed 
      for the quantification of six pyrethroid pesticides in water and honey samples. 
      Several important parameters affecting the extraction efficiency for six 
      pyrethroid pesticides were optimized in sequential order, including ionic 
      strength, extraction time and desorption time. Under the optimized conditions, 
      this method showed wide linearity ranging from 0.5 microg/L to 50 microg/L with 
      correlation coefficients (R2) higher than 0.990. The limits of detection (LODs) 
      ranged from 0.07 microg/L to 0.20 microg/L at a singal-to-noise ratio of 3. The relative 
      standard deviations (RSDs) ranged from 3. 8% to 8. 1%. Satisfactory recoveries (> 
      78.4%) were obtained for the simultaneous analysis of the six pyrethroid 
      pesticide residues in river water, fish-pond water and two honey samples. This 
      method is sensitive and simple. It can meet the actual requirement for the 
      analysis of trace analytes from environmental water and honey samples.
