QUANTITATIVE ANALYZING METHOD OF FLUORINE

摘要

PROBLEM TO BE SOLVED: To provide a quantitative analyzing method of fluorine determining fluorine contained in a solid sample precisely and rapidly.

SOLUTION: Fluorine contained in the sample determined precisely and rapidly by processes for: burning the sample in a pressure-resistant container, in which an absorbing liquid is injected, under an oxygen atmosphere having pressure higher than atmospheric pressure; recovering the absorbing liquid to adjust the pH thereof to 5.0-5.5; and measuring the potential of the absorbing liquid adjusted in its pH.
