EXPOSURES OF BIOLOGICAL SYSTEMS TO INORGANIC FLUORIDE OXIDIZING AGENTS. VOLUME 2. FLUORIDE ANALYSIS BY CHEMICAL METHODS

Abstract : Methods are described for assaying the fluoride content of ashed samples of plant and animal tissues. Using the Hall method, submicrogram quantities of fluoride were measured and a new procedure was devised to measure fluoride in a 1 to 8 microgram range. Modification of the Weinstein procedure, in which an AutoAnalyzer is used, permitted rapid and semiautomated analysis of samples containing 2.5 to 100 micrograms of fluoride.
