Abstract
solid-phase microextraction (SPME) coupled with high-performance liquid chromatography(HPLC) for the analysis of triazine is described. Carbowax/ templated resin (CW/TPR, 50mm), polydimethylsiloxane/divinylbenzene (PDMS/DVB, 60 mm), ploydimethylsiloxane (PDMS, 100mm) and polyacrylate (PA, 85mm) fibers were evaluated in this work. CW/TPR and PDMS/DVB fibers were selected for further were selected for further study. Several parameters of the extraction and desorption procedure were studied and optimized (such as types of fibers, extraction time, temperature, pH, ionic strength and elutropic strength of samples, desorption mode, desorption time, compositions of solvent for desorption, soaking periods and the flow rate during desorption period). Both CW/TPR and PDMS/DVB fibers turned out to be excellent. They were recommended for thr determination of environmental water samples, since a siple calibration curve method can be used. The detection limits of this method are at the levels of ng/mL.
