Fluorometric Determination of Uranium in Zirconium and Hafnium
The extraction of microgram quantities of uranium with ethyl acetate was found suitable for the determination of trace amounts of uranium in zirconium. Ralf-gram samples are dissolved in nitric and hydrofluoric acids, the hydrofluoric acid is removed, and the solution is made up to a definite volume. An aliquot is pipetted into a vial containing; a salting agent and the uranium extracted with ethyl acetate. The amount of uranium in the organic layer is determined fluorometrically. Any quenching occurring is compensated by control standards. The concentration of uranium in hydrofluoric-nitric acid pickling baths is determined by the standard addition of uranium to a duplicate of the sample being analyzed. Study of the variables in fluorometric determination of uranium has indicated those that must be controlled for best precision and accuracy. (auth)
