Estimation of uranium in columbite-tantalite samples: A method for sample solution preparation for fluorimetric estimation.

Abstract

A method has been developed for obtaining a clear solution of columbite-tantalite samples in nitric acid medium before the fluorimetric estimation of uranium. Ammonium hydrogen fluoride is used to keep tantalum, niobium and titanium dissolved in the acid medium. The excess of fluoride is complexed with boric acid. The method has been successfully applied to… (More)
