Description/Abstract | A volumetric method is presented for the determination of fluoride in inorganic samples containing high levels of metal ions as well as the anions nitrate, chloride, and perchlorate After preliminary separation of the fluoride bv pyrolysis, cerous fluoride is precipitated stoichiometrically at pH 1.75 with a measured excess of cerium(IfI), and the excess cerium is back-titrated with EDTA to an arseneazocresol red end point. Sulfate and large amounts of borate interfere. (auth) |
