Abstract
1. Способ очистки висмута от полония из расплава, отличающийся тем, что предварительно металлический висмут расплавляют с флюсом гидроокиси натрия, затем в расплав висмута вводят металлический натрий или висмут-натриевую лигатуру в эффективном для удаления полония количестве натрия, ведут процесс при температуре 340-360°С и перемешивании расплава, после чего очищенный от полония расплав отстаивают и щелочной плав удаляют.2. Способ по п.1, отличающийся тем, что количество вводимого металлического натрия или натрия в висмут-натриевой лигатуре составляет 0,1-0,3 мас.%.3. Способ по п.1, отличающийся тем, что в качестве висмут-натриевой лигатуры используют очищенный от полония висмут с остатком не прореагировавшего натрия.4. Способ по п.1, отличающийся тем, что процесс ведут в течение 2-3 ч с отстаиванием расплава в течение не менее одного часа.5. Способ по п.1, отличающийся тем, что очищенный от полония расплав висмута дополнительно обрабатывают смесью натриевой щелочи и нитрата натрия в массовом соотношении натриевой щелочи и нитрата натрия равном 3:1, соответственно, при этом берут избыток нитрата натрия 50-100 мас.% от стехиометрического количества, процесс ведут при 340-360°С при перемешивании с последующим отстаиванием и удалением щелочно-нитратного плава.1. The method of purification of bismuth from polonium from the melt, characterized in that the metal bismuth is first melted with a flux of sodium hydroxide, then sodium metal or bismuth-sodium ligature is introduced into the bismuth melt in an effective amount of sodium to remove polonium, the process is conducted at a temperature of 340-360 ° C and stirring the melt, after which the melt purified from polonium is defended and the alkaline melt is removed. 2. The method according to claim 1, characterized in that the amount of metallic sodium or sodium introduced in the bismuth-sodium ligature is 0.1-0.3 wt.%. 3. The method according to claim 1, characterized in that bismuth purified from polonium with the remainder of unreacted sodium is used as the bismuth-sodium ligature. The method according to claim 1, characterized in that the process is conducted for 2-3 hours with sedimentation of the melt for at least one hour. The method according to claim 1, characterized in that the bismuth melt purified from polonium is additionally treated with a mixture of sodium alkali and sodium nitrate in a mass ratio of sodium alkali and sodium nitrate equal to 3: 1, respectively, while taking an excess of sodium nitrate 50-100 wt.% from a stoichiometric amount, the process is carried out at 340-360 ° C with stirring, followed by sedimentation and removal of alkaline-nitrate melt.
