DESCRIPTION
General description
Triethanolamine (TEA) belongs to the family of ethanolamines. It includes the properties of both amines and alcohols.^[1]
Application
Triethanolamine may be used as a derivatizing reagent for the determination of boric acid in water samples using gas chromatography-mass spectrometry technique.^[2]Addition of triethanolamine to an acidic buffer facilitates the determination of fluoride in inorganic orthophosphates by using a fluoride-selective electrode.^[3]
