Summary
The use of polymeric fullerene to coat the fiber used in solid-phase microextraction (SPME) is described. The efficiency, sensitivity, and reliability of the new coated fibers have been investigated for the extraction of three kinds of sample, BTEX, naphthalene congeners, and phthalic acid diesters, from the headspace of water samples. Detection limits at the ng L−1 to μg L−1 level were achieved by use of GC-FID. A wide linear range was obtained with precision typically below 12% relative standard deviation for phthalic acid diesters. The effects on extraction efficiency of factors such as addition of salt, stirring, and exposure time were also studied.
