| Abstract: | A procedure was developed for the gas-chromatographic determination of aliphatic amines C7–C20 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. |
