Изобретение относитс к способам получени менделеви в одновалентном состо нии и может быть использовано дл отделени менделеви от других актинидов и лантанидов.The invention relates to methods for producing mendelevium in the monovalent state and can be used to separate mendelevium from other actinides and lanthanides.
По этому способу сол нокислый водноспиртовой , например водно-этанольный раствор менделеви , наход щегос в более окисленных формах, обрабатывают металлическим магнием в присутствии трихлорида самари , иттерби или европи .According to this method, hydrochloric water-alcohol, for example, ethanol-water solution of Mendeleev, which is in more oxidized forms, is treated with metallic magnesium in the presence of samarium, ytterbium or europium trichloride.
Дл выделени одновалентного менделеви из раствора последний обрабатывают спиртовым например этапольным, раствором хлорида цези .In order to separate monovalent mendeleev from solution, the latter is treated with alcohol, for example, a statiol, solution of cesium chloride.
Пример 1. К 1 мл водно-спиртового раствора менделеви , содержащего 100 мг ЕиС1з и 2,5 ммоль воды, добавл ют 50 мг магни в виде стружки толщиной 0,1 мм и 1 мл 7 М раствора НС1 в этаноле. При этом европий восстанавливаетс до двухвалентного состо ни и образует осадок ЕиСЬ. Менделевий при восстановлении европи переходит в одновалентное состо ние и не захватываетс осадком . Дл извлечени менделеви в одновалентном состо нии примен ют его сокристаллизацию с CsCl. Дл этого к содержимому пробирки добавл ют 0,2 мл насыщенного раствора CsCl в спирте. Выпадающий при этом осадок CsCl количественно захватывает менделевий .Example 1. To 1 ml of a water-alcohol solution of Mendelev, containing 100 mg of EuCl3 and 2.5 mmol of water, add 50 mg of magnesium in the form of chips 0.1 mm thick and 1 ml of a 7 M solution of HCl in ethanol. At the same time, europium is reduced to the bivalent state and forms the precipitate EuCL. Mendelevium, when recovered, transfers europium to the monovalent state and is not entrained in sediment. To remove the monovalent monovalent state, its cocrystallization with CsCl is used. For this purpose, 0.2 ml of a saturated solution of CsCl in alcohol is added to the contents of the tube. The precipitated CsCl precipitate quantitatively captures mendelevium.
Пример 2. К 1 мл водно-этанольного раствора менделеви , содержащего 50 мг YbCb и 2,5 ммоль воды, добавл ют 50 мг металлического магни в виде стружки толщинойExample 2. To 1 ml of a water-ethanol solution of Mendeleev, containing 50 mg of YbCb and 2.5 mmol of water, 50 mg of metallic magnesium are added in the form of chips with a thickness of
0,1 мм и 7 М раствор НС1 в этаноле. При этом происходит восстановление иттерби до двухвалентного состо ни , а менделевий восстанавливаетс до одновалентного состо ни . Дл выделени менделеви его осаждают с0.1 mm and 7 M solution of HC1 in ethanol. When this happens, ytterbium is reduced to the divalent state, and mendelevium is restored to the monovalent state. To isolate it, mendelev is precipitated with
хлоридом цези , как это указано в примере 1. Выпадающий осадок количественно захватывает менделевий.cesium chloride, as indicated in example 1. The precipitate quantitatively captures mendelevium.
