    Abstract:
    A method for the preparation of a novel gamma-Al2O3 coated layer on fibers for solid-phase microextraction (SPME) was developed. The adsorption and desorption properties of the coated fibers were studied by the extraction of some volatile organic compounds such as benzene, toluene, ethylbenzene and xylene isomers (BTEXs) from aqueous samples. The calibration graphs were linear in the range 0.01 mg/L to 3 mg/L and the detection limits for BTEX compounds were between 1 microg/L and 10 microg/L. Also the gamma-Al2O3 coated fibers exhibited a good thermal stability (to 350 degrees C ) and reproducibility with relative standard deviation of 8.3%. It can be used to determine organic compounds in the real gaseous samples.
