Abstract
An accurate determination of fluoride has been an important analytical problem for some time. As yet there is no simple acceptable method of fluoride determination although volumetric gravimetric and instrumental methods have all been tried. Of the various methods the gravimetric precipitation of lead chloride fluoride is one of the most common. This method gives reasonably accurate results and requires no special or expensive laboratory equipment. Within the past ten years this method has been modified for precipitation at a low pH. Work has also been carried out on a method of fluoride determination using a precipitate of lead bromide fluoride. The purpose of this work was to investigate the determination of fluoride using a precipitate of lead fluoride iodide. The goals of this research were threefold: 1) to determine the proper control of the variables 2) to observe if the method is pH sensitive and 3) to see if this method deserves further investigation for precipitation in the presence of carbonate, borate, etc. This work is part of a sequence of fluoride determinations using precipitates of lead fluoride halides begun by Dr. R. A. Bournique.
