In the determination of fluorine, recovery of fluorine was significantly raised by steam-distillation of silicate-containing sulfuric acid. Accurate estimation of low fluorine content in the sample became possible by the use of this method and was found that the steam-distillation using sulfuric acid is much better the determination of fluorine than that using perchloric acid.
