摘要
A method for detecting and quantifying haloether contamination in aqueous samples. A flow state is artificially induced upon an aqueous sample and a solid phase microextraction (SPME) fiber, upon which an electric potential is applied, is exposed to the flowing aqueous sample in direct immersion mode. Halide ions liberated from electrophoretically dehalogenated haloether compounds contained in the aqueous sample are absorbed upon the SPME fiber, then later desorbed at a gas chromatograph, separated into individual halide ions and analyzed by mass spectrometry. Effects of various parameters such as absorption time, sample pH, salt content, applied voltage, SPME fiber type, flow rate and background matrix are also described.
