Potentiometric method for the determination of inorganic fluoride in biological material.

Abstract

A number of methods for the determination of inorganic fluoride in biological material are available. These are dependent on the formation of hydrogen fluoride which is separated by means of diffusion or distillation; it is collected in a form suitable for the production of a dye- complex which may be determined colorimetrically.
