Determination of Fluoride in Fluomica and Fluomica-Alumina Composites with the Fluoride Electrode

Abstract

Fluoride is determined in barium fluomica and barium fluomica-alumina composites by direct potentiometric measurement with a fluoride specific-ion electrode. Measurements at pH 8 and pH 12 are compared using different methods of sample decomposition and preparation. Since the fluoride recoveries are the same in each case, direct measurement in an aqueous sodium carbonate medium is the method of choice. This method is simple and rapid since the addition of complexing and buffering agents is not required nor is the adjustment of pH necessary.
