Abstract
An X-ray fluorescence spectrometric method is described for the determ ination of uranium in liquid samples by absorbing drops of solution on cellulose discs. Internal standards thorium, strontium or yttrium are added in the uranium solution to follow the non-uniform absorption of the liquid on the disc. A precision of better than +/-0.5% is obtaine d for uranium determination with all the three internal standards. The method was also employed to determine uranium in the presence of plut onium and americium without any interference effects.
