摘要：
Solid-phase microextraction coupled with HPLC for the analysis of the aromatic amines is described. Four kinds of fiber [Carbowax/templated resin (CW/TPR), Carbowax/divinylbenzene, poly(dimethylsiloxane)/divinylbenzene (PDMS/DVB), and polyacrylate] were evaluated for extraction of the aromatic amines. CW/TPR and PDMS/DVB were selected for further study. The parameters of the desorption procedure [such as desorption mode, the composition of the solvent for desorption, the period that the fiber was flushed by the mobile phase (desorption period), the duration of fiber soaking, and the now rate of the mobile phase during the desorption period] were studied and optimized. The effects of the properties of analytes and fiber coatings, carryover, duration and temperature of absorption, pH, ionic strength, and elutropic strength, of samples were also investigated. The method was applied to environmental samples (lake water).
