Abstract: A facile and rapid method for the determination of ethanolamine(EA) and triethanolamine(TEA) in diethanolamine (DEA) by using hydrogen flame ionization detector has been developed.It was operated on a HP-5 30 m×0.32 mm×0.25 μm capillary column.Triethylene glycol(TEG) was used as internal standard.The average recoveries were from 93.17% to 101.50%, at relative standard deviations from 1.54% to 2.15%.
Key words: capillary gas chromatography, diethanolamine, ethanolamine, triethylene glycol
