Abstract
A method is presented for the determination of 22 organic compounds in polluted groundwaters. The method includes liquid-liquid extraction o f the base/neutral organics from small, alkaline groundwater samples, followed by derivatisation and liquid-liquid extraction of phenolic co mpounds after neutralisation. The extracts were analysed by capillary gas chromatography. Dual detection by flame ionisation and electron ca pture was used to reduce analysis time.
