Abstract
Solid-phase microextraction (SPME) coupled with high-performance liquid chromatography (HPLC) for the analysis of aromatic amines is described. Carbowax/templated resin (CW/TPR, 50mm), polydimethylsiloxane/divinylbenzene (PDMS/DVB, 60 mm) and polyacrylate (PA, 85mm) fibers were evaluated in this work. CW/TPR and PDMS/DVB fibers 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 time, soaking periods and the flow rate during desorption period). PDMS/DVB fiber was recommended for the determination of environmental water samples, since a simple calibration curve method can be used. The detection limits of this method are at the levels of ng/mL.
