摘要：
A series of commercial fibers (carbowax-divinylbenzene, carboxen-polydimethylsiloxane, polydimethylsiloxe-divinylbenzene, divinylbenzene/carboxen polydimethylsiloxane and polyacrylate were evaluated for pre-concentration of acetone in cyclohexane by solid phase microextraction (SPME). Fibers were evaluated in terms of exposure time, extraction temperature and stirring. Best results were observed for divinylbenzene/carboxen polydimethylsiloxane with extraction temperature of 40 degrees C and 15 min of extraction time. The quantification range was situated at ppb level. Evaluation of the method in an industrial polymerization plant effluent was shown to be efficient. (c) 2006 Elsevier B.V. All rights reserved.
