Last years, the usefulness of the use of carbon nanotubes (CNTs) as sorbent material have been demonstrated for a wide variety of compounds. In this work, it has been demonstrated for first time that immobilized carboxylated single-walled carbon nanotubes (c-SWNTs) offer clear advantages over the use of CNTs. The higher adsorption capacity has been attributed to the special orientation of c-SWNTs molecules on the glass surface. The potential of this new sorbent was evaluated for the preconcentration of non-steroidal anti-inflammatory drugs (NSAIDs) from urine samples. Purified samples were analysed by capillary electrophoresis-mass spectrometry detection allowing the determination of 1.6 to 2.6 microg/L of NSAIDs with only 5 mL of sample. The precision of the method for the determination of real spiked urine samples ranged from 5.4 to 7.4% and the recoveries from 98.6 to 102.2%.
