The determination of acrylamide in water by using electron-capture gas chromatography

摘要: A method is described for the determination of residual acrylamide in water at levels likely to arise from use polymers and copolymers treatment. After bromination sample, α,β-dibromopropionamide obtained extracted with diethyl ether extract analysed by electron-capture gas chromatography. Replicate samples added River Thames concentrations 500, 50, 5 0·25 µg 1–1 were relative standard deviations ±5, ±9 ±10 per cent., respectively.A detection limit 0·1 was achieved determined a deviation cent. Yields α, β-dibromopropionamide vary quality, ultraviolet light intensity other reaction conditions. To overcome effects caused these variables, when present, an internal standardisation procedure used. The remained but this ±20
