TI  - [Determination of the trace residues of four organochlorine pesticides in 
      agricultural products by high performance liquid chromatography with modified 
      multi-walled carbon nanotubes as solid phase extraction adsorbent].
PG  - 966-70
AB  - A novel method for the simultaneous determination of the trace residues of four 
      organochlorine pesticides such as p,p'-DDD, p,p'-DDT, o,p'-DDT and p,p'-DDE in 
      agricultural products by multi-walled carbon nanotubes (MWNTs) modified by acid 
      oxidation on the surface as solid phase extraction (SPE) adsorbent coupled with 
      high performance liquid chromatography (HPLC) was developed. The effects of the 
      surface acid oxidation, SPE operations and HPLC conditions on the determination 
      of the four pesticide residues were investigated. Under the optimized 
      experimental conditions, the novel method provided wide linear ranges for the 
      pesticides with correlation coefficients of 0. 997 8 - 0. 999 5, the detection 
      limit was 0.050 mg/L for each pesticides. The recoveries from the samples spiked 
      with the pesticide standards at three concentration levels of 0.10, 2.0 and 50 
      mg/L were in the range of 78% - 104% with the relative standard deviations (RSDs) 
      of 2.7% -7.6%. This study indicated the MWNTs SPE was an efficient clean-up 
      method to agricultural products (included dried orange peel, ginseng, cabbage and 
      tea). The proposed method showed the advantages of accuracy and sensitivity, and 
      can meet the requirements for the determination of low residue pesticide in 
      agricultural products. The study provides a useful method for the analysis of 
      trace substance of agricultural products.
