A micro analytical method has been established for aliphatic lower primary and secondary amines in environmental water and sediment. Amines were distilled and allowed to react with benzenesulfonyl chloride under an alkaline condition. The derivatized compounds were extracted with benzene under an acidic condition and subjected to a determination by GC/MS. This method has been successfully applied for a simultaneous determination of primary and secondary amines with recovery over 80%, except for methylamine, and C.V. below 7%, except for methyl and dimethyl amines; moreover, the detection limit were 0.1 micro g/L for all of the amines determinated. This method is excelent also in sensitivity, is sufficiently applicable to environmental samples.
