Gas-chromatographic determination of aliphatic amines in natural surface water and wastewater

A procedure was developed for the gas-chromatographic determination of aliphatic amines C 7 –C 20 with prederivatization by N -methyl-bis(trifluoroacetamide), in the concentration range of natural surface water, to 10 −4 -1 mg/L, and wastewater, to 10 −3 -1 mg/L. The conditions were optimized for th...

Description
Summary:	A procedure was developed for the gas-chromatographic determination of aliphatic amines C 7 –C 20 with prederivatization by N -methyl-bis(trifluoroacetamide), in the concentration range of natural surface water, to 10 −4 -1 mg/L, and wastewater, to 10 −3 -1 mg/L. The conditions were optimized for the extraction preconcentration of aliphatic amines with toluene from natural surface water and wastewater. The detection limit for aliphatic amines at a signal-to-noise ratio of 3: 1 was 50 ng/L.
