摘要

The amount of adsorbable protactinium and its distribution coefficient (DC = counts min-1 g of glass-1/counts min-1 ml-1 solution) with 60-80 mesh unfired Vycor glass has been determined for Pa233 tracer solutions containing 4 to 100 g Th/liter, 0.5 to 12 M HN03, 0 to 0.04 M HF, and 0 to 0.4 M Al(N03)3.nThe addition of aluminum partially cancelled the effects of fluoride, but the maximum was still only half that of thorium-nitric solution containing no fluoride or aluminum. For example, the coefficient was 3000 for 10 M HNO3, 100 g Th/liter, 300 with 0.04 M HF present, and 1500 with 0.04 M HF, 0.4 M AI present. The amount of unadsorbable protactinium depended only on the nitric acid concentration, ranging from a maximum value of about 7％ in 0.5 M HNO3 to less than 2％ in solutions containing more than 3 M HNO3. Hot-cell experiments are recommended to test the application of this principle for adsorption of protactinium from short-cooled high-burnup thorium.
