Title: Ion-selective electrode in determining fluorine in binary fluorides of metals of groups II-V

Abstract

The authors have developed a method of determining fluorine by ion-selective electrode techniques in specimens containing mixtures of the fluorides of magnesium and the rare-earth elements (REE), as well as scandium and bismuth. The specimens after treatment at high temperatures are sparingly soluble at room temperature in water and also in aqueous solutions of acids and bases. The authors found that a mixture of KNaCO/sub 3/ and K/sub 2/S/sub 2/O/sub 8/ with a mass ratio of 2:1 was an effective flux for MgF/sub 2/-MeF/sub 3/ specimens, where Me is an REE ion. The combined method of analyzing binary mixtures of fluorides (Mg and REE, Sc and Bi) which provides satisfactory accuracy and reliability in determining the fluoride and two different metals whose compounds may have various ratios in the samples.
