一般描述

Triethanolamine (TEA) belongs to the family of ethanolamines. It includes the properties of both amines and alcohols.

应用

Triethanolamine may be used as a derivatizing reagent for the determination of boric acid in water samples using gas chromatography-mass spectrometry technique. Addition of triethanolamine to an acidic buffer facilitates the determination of fluoride in inorganic orthophosphates by using a fluoride-selective electrode.
