Abstract  

The separation of fluorine was studied by several inorganic ion exchangers. A high yield of adsorption for fluorine was obtained using hydrated tin dioxide in 1N nitric acid. Fluorosilicate can be separated under the same conditions. It was also found that fluorine and fluorosilicate could be separated substoichiometrically. The substoichiometric separation was applied to the determination of oxygen in silicon crystals by radioactivation analysis. The concentration of oxygen was 28 ppm and agreed with that from a non-destructive method.
