AB  - A novel method using a microcolumn packed with single-walled carbon nanotubes 
      (SWNTs) as a new adsorption material was developed for the preconcentration of 
      trace Cu, Co and Pb in biological and environmental samples prior to their 
      determination by inductively coupled plasma mass spectrometry (ICP-MS). SWNTs 
      oxidized with concentrated nitric acid have been proved to possess an exceptional 
      adsorption capability for the analytes due to their surface functionalization. 
      The adsorption behaviors of the analytes on SWNTs under dynamic conditions were 
      studied systematically. The main factors influencing the preconcentration and 
      determination of the analytes (pH, sample flow rate and volume, eluent 
      concentration and interfering ions) have been examined in detail. Under the 
      optimum conditions, the detection limits for Cu, Co and Pb were 39, 1.2 and 5.4 
      pg mL(-1), respectively; the relative standard deviations (RSDs) were found to be 
      less than 6.0% (n=9, c=1.0 ng mL(-1)). This method was validated using a 
      certified reference material of mussel, and has been successfully applied for the 
      determination of trace Cu, Co and Pb in real water sample with the recoveries of 
      96.0-109%.
