The adsorption process of 2,4,6-trichlorophenol (TCP) by carbonaceous materials, such as Carbopack
B graphitized carbon black, Vulcan XC72 carbon black and two kinds of multi-walled carbon nanotubes,
have been studied. The adsorption kinetics was best represented by the pseudo-second order
kinetic model. Adsorption took place in accordance with the Freundlich equation. The materials were
used to prepare novel, solid-phase microextraction (SPME) fibers. The efficiency of the fibers was
evaluated using a gas chromatograph with an atomic emission detector for the extraction of TCP
from the headspace of aqueous samples. Both the carbon nanotubes and carbon blacks coated fibers
were of higher quality than commercially available fibers prepared from polydimethylsiloxane and
polyacrylate. The results proved the ability of the proposed SPME fibers to detect TCP in water.
