Determination of ethylenethiourea in water samples by gas chromatography with alkali flame ionization detection and mass spectrometric confirmation
article
A gas chromatographic method with alkali flame ionization detection and mass spectrometric confirmation is described for the determination of ethylenethiourea (ETU) in water samples. The method is based on the extraction of ETU with dichloromethane in the presence of thiourea and sodium L-ascorbate. The limit of detection is less than 0.1 μg/l in water. The average recovery in groundwater is 71%. Several hundred samples of groundwater and river water were analysed over a 2-year period.
