摘要：

A solid-phase microextraction (SPME) technique was used to determine haloethers in water. Three kinds of fibres [100 and 7 mu m polydimethylsiloxane (PDMS) and 85 mu m polyacrylate fibres] were used and compared. The effects of the structure and physical properties of the analytes, sample volume, duration of absorption and desorption, temperature of absorption, carryover, pH, ionic strength and elutropic strength of samples were investigated. It is concluded that the 100 mu m PDMS fibre is the most suitable fibre for the analysis of semi-volatile polar haloethers in water using the SPME technique. This method was applied to environmental samples (tap and lake water) using a simple calibration curve.
