Determination of Water in Plutonium Dioxide

Techniques developed to very effectively apply automatic Karl Fischer reagent titration to the determination ofH solids were used to determine the moisture content of samples ofplutonium dioxide powder under the constraints imposed by the necessity of working in a glove box. The moisture contents of three samples were found to be 0.2934%, 0.7298% and 0.4640%. The estimate of the relative standard deviation of the mean for three determinations on the 0.2934% sample was 0.0091. The method apparently has potential as the basic reference method for the determination ofH plutonium dioxide, as a means of standardizing other methods, and as a diagnostic tool. 2O in2O in
