Abstract
A method for isolation and electroplating of210Po is described. Natural samples of autunite, after pretreatment, were dissolved in dilute hydrochloric acid and the solution was passed through a chromatographic partition column with di (2-ethylhexyl) phosphoric acid as stationary phase. Uranium and its daughters were strongly retained in the column. The210Po fraction was eluted with citric acid solution, then evaporated almost to dryness. Next, electroplating was carried out for 18 h, at 5–10 mA current, using an electrolyte bath of oxalic acid solution. The yield of recovery of radiochemically pure210Po was about 95% of the initial210Po activity.
