Web10 ml of the TSI reagent are added; the beaker is covered with a watch glass and gently stirred on a magnetic stirrer. After 5 minutes reaction time, 0.5 ml of water is added to remove the excess of TSI. After a further minute, the solution is made up to 50-60 ml with acetonitrile and titrated with TBA-OH 0.1 mol/l to 2 equivalence points. WebTriethanolamine (TEA) belongs to the family of ethanolamine. It includes the properties of both amines and alcohols. Addition of TEA to an acidic buffer facilitates the determination of fluoride in inorganic orthophosphates by using a fluoride-selective electrode.
