Removal of polonium by spontaneous deposition onto bismuth powder (referred to as scrubbing) following dissolution of irradiated bismuth and denitration is the step normally employed in the processing scheme as a means of concentration from relatively dilute solutions. This separation and concentration, and to some extent purification, is achieved by allowing the solution, in high chloride-ion concentration, to flow through a fixed bed of bismuth powder. A variation of this process was investigated utilizing the agitation of the bismuth powder with an inert gas to effect a more intimate contact with the polonium. The effect of bismuth particle size (surface area), quantity of powder used, rate of polonium deposition, initial polonium concentration, and the manner and extent of agitation were studied. The results indicated quantitative yields were realized by this modified process.
