Determination of Fluorine in Certain FLuoro-Organic Compounds to Water
Abstract
A method for the determination of fluorine in sodium fluoroacetate, methyl fluoroacetate, 2-fluoroethanol, and diisopropyl fluorophosphate in water is described. It involves addition of the aqueous solution of the fluoro-organic compound to potassium meta periodate, silver perchlorate, perchloric acid and glass wool; the mixture is refluxed, then distilled: the temperature is held at 135-145 deg C by the addition of water until 100 ml of distillate is collected. Aliquots of the distillate are then analyzed for fluoride ion by titrating with thorium nitrate solution using Solochrome Brilliant Blue as indicator. From 97-100% of the fluorine was removed. Ions commonly present in potable waters do not interfere seriously. The time required for a determination is about one hour.
