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

摘要

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.
