      chromatography coupled with solid-phase extraction using multiwalled carbon 
      nanotubes as adsorbent].

AB  - A multi-residue analytical method based on solid-phase extraction (SPE) with 
      multiwalled carbon nanotubes (MWCNTs) as sorbent was developed. The determination 
      of the sulfonamides (SAs) in pork and chicken was carried out by high performance 
      liquid chromatography-ultraviolet detection (HPLC-UV). The clean-up conditions 
      were optimized. The analytes were extracted by acetonitril and cleaned-up by 
      MWCNTs SPE cartridge. The extract was redissolved with the Na2HPO4 buffer (pH 
      5.5-6.0) for loading, and was washed with acetone-hexane (5:95, v/v), then eluted 
      with acetone-dichloromethane (1:1, v/v) from the column. The mobile phase used in 
      the chromatographic separation consisted of a binary mixture of acetonitrile and 
      50 mmol/L NaH2PO4 with the volume ratio of 7:3. A wide linear range was 0.01-1.00 
      mg/L with the correlation coefficients above 0.998. The limits of detection (S/N 
      = 3) were 0.003 mg/L, and the limits of quantification (S/N = 10) were 0.01 mg/L. 
      The average recoveries were over 70% for the nine SAs in the spiked range of 
      0.02-0.2 mg/kg, with the relative standard deviations (RSDs) lower than 8%. This 
      study indicated that the MWCNTs SPE cartridge is efficient for the clean-up of 
      the SAs in animal tissues or products, and the method is simple, accurate and 
      suitable for the quantification of the SAs residues.
