title: Automated determination of fluoride using silicone-facilitated diffusion.
abstract: An automated procedure for the determination of fluoride in biological fluids that uses silicone-facilitated diffusion at room temperature to separate fluoride from other sample constituents is described. Fluoride is measured by its ability to quench the fluorescence of a morin-thorium complex. The procedure appears to be free of significant interferences and is capable of measuring fluoride in the submicromolar range.
