The aim of this project was to develop a method for the determination of epichlorohydrin in drinking water. First, epichlorohydrin was studied on gas chromatography (GC) to determine the retention time. Then, epichlorohydrin was used to optimise the GC parameters : best detector, detector temperature, total detector flow, injector temperature and column temperature program. Secondly, epichlorohydrin was extracted by Solid Phase Micro-Extraction (SPME) and by Solid Phase Extraction (SPE) and analysed by GC to optimise the extraction mode parameters : SPME extraction mode, salt saturation, fibre selection, sample temperature, fibre placement, stirring and vibration, extraction time ; SPE tube selection, volume of extraction, extraction flow rate, salt saturation, drying process, solvent of elution, volume of solvent. Thirdly, the limit of detection of both extraction modes by GC was looked at to decide on the best extraction technique for epichlorohydrin. Fourth, epichlorohydrin was extracted by SPME direct immersion and analysed by gas chromatography/mass spectroscopy (GC/MS). A calibration curve was obtained with the analyses of Milli-Q water sample spiked with epichlorodydrin. A limit of detection was determined at 0.38 μg/L. Finally, water samples from the Adelaide distribution system were analysed by GC/MS through two columns but epichlorohydrin could not be separated from bromodichloromethane present in drinking water from the disinfection process. / Thesis (MEng(HydrologyWaterResources))--University of South Australia, 2003.
