A simple and rapid method for the determination of total fluoride content in uranium tetranuoride is based on separation of the fluoride ion by means of a cationic ion exchange resin and titration of the liberated hydrofluoric acid with sodium hydroxide. The solid sample of uranium tetrafluoride is dissolved in a mixture of sodium hydroxide and hydrogen peroxide and after dilution the solution is passed through the ion exchange column. The above mixture of reagents is also suitable for dissolving UO₂, U₃O₈, UO₃, and UO₂F₂, all of which may be present in lesser or larger amounts in technical uranium tetrafluoride. A determination requires only 15 to 20 minutes and no complicated or expensive apparatus is needed. The standard deviation for 15 determinations was 0.13 on a value of 23.91% fluorine.
