Determination of Octadecylamine in Water by Quantitative High Performance thin Layer Chromatography

Abstract

Octadecylamine (ODA) was isolated from water by solvent extraction with ethylene dichloride or trapping on a micro Chromosorb column. The ODA in the extract or column eluent was chromatographed on a high performance silica gel layer, detected by spraying with ninhydrin, and quantified by reflectance densitometry. Recovery at 3 ppm averaged 81.3% using extraction and 94.0% with the column. Recovery at 0.3 ppm was 94.2% using the column procedure.
