Rapid potentiometric methods for uranium and for analysis of mixtures using potassium bromate

Abstract

This investigation is an application of the method involving determination of uranium(VI) based on reduction to uranium(IV) with zinc metal in acidic medium, and then oxidation by adding a known excess of bromate. Boiling to expel the liberated bromine then adding sulfite and 1 ml 10% sulfuric acid, expel excess sulfite, cooling and titrating the liberated bromide with silver(I), using silver amalgam as indicator electrode in conjunction with calomel electrode. Binary and ternary mixtures are successfully analyzed. The present methods have advantages over the classical ones of being simple, rapid, and reliable.
