METHOD OF ENRICHMENT OF THE ISOTOPES OF SELENIUM Russian patent published in 2007 - IPC B01D59/00 B01D59/20 C01B19/02 

FIELD: chemical industry; methods of enrichment and separation of the isotopes of selenium.

SUBSTANCE: the invention is pertaining to the field of separation of the isotopes, in particular, the process of separation of the stable isotopes by the gas centrifugation. In compliance with the method the enrichment of the isotopes of selenium is exercised by the gas centrifugation of the volatile chemical compound of selenium, in the capacity of which they feed to the gas centrifugation the volatile compound of selenium, which does not contain the fluorine atoms, such as hydrogen selenide (H₂Se) or selenophene (C₄H₄Se) or dimethylselenium (Se(CH₃)₂). The technical result of the invention is the increased purity of the produced isotopic selenium at the expense of exception of the fluorine-containing components at the simultaneous improvement of the process safety.

EFFECT: theinvention ensures the increased purity of the produced isotopic selenium due to exception of the fluorine-containing components at the simultaneous improvement of the process safety.
