[en] A method for isolation and electroplating of ²¹⁰Po 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. The ²¹⁰Po 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 pure ²¹⁰Po was about 95% of the initial ²¹⁰Po activity. (author) 3 refs.; 2 figs.; 1 tab
