Abstract
The determination of fluoride is important both in the analysis of organic compounds and in the analysis of ores and minerals. The precipitation of lead chloride fluoride and titration of the chloride in this precipitate for an indirect fluoride determination is among the most common macro methods used. A literature search, however, revealed dissatisfaction with results of this method. A limited testing of the various procedures available for forming the precipitate, by an industrial research team, showed that correct composition of the precipitate has not yet been achieved. A gravimetric analysis alone is not possible when anions of weak acids are present because precipitation or adsorption of these may cause high results. The purpose of this work was to attempt to develop a low pH, gravimetric procedure which would eliminate this interference, and to investigate some of the variables which affect the composition of the precipitate.
