Abstract

1. Способ рафинирования висмута от полония, включающий нагрев и последующую обработку расплава, отличающийся тем, что, с целью более полной очистки висмута, в расплав сначала вмешивают металлический цинк при 350-400°C, а затем обрабатывают последовательно едкой щелочью и элементарной серой.2. Способ по п.1, отличающийся тем, что, с целью снижения перехода полония в газовую фазу, в расплав перед обработкой едкой щелочью вводят селитру.1. A method of refining bismuth from polonium, including heating and subsequent processing of the melt, characterized in that, in order to more thoroughly clean the bismuth, metallic zinc is first mixed in the melt at 350-400 ° C, and then treated with caustic alkali and elemental sulfur. 2 The method according to claim 1, characterized in that, in order to reduce the transition of polonium into the gas phase, nitrate is introduced into the melt before being treated with caustic alkali.
