METHOD USED FOR SEPARATION OF THE ISOTOPES Russian patent published in 2008 - IPC B01D59/10 B01D59/20 B01D59/28 

FIELD: chemical industry; other industries; methods of separation of isotopes.

SUBSTANCE: the invention is pertaining to the method of separation of isotopes, i.e. to production of the isotopically pure fractions by means of division of the isotopic mixtures of the natural origin into the ingredients. In the capacity of the ligand added to the ingredients, which should be isotopically separated, use hydrogen. At that so produced compound is gaseous at the temperatures and pressures used in practice. In the more concrete formulation the invention is pertaining to the method of production of the isotopically pure ²⁸SiH₄ in the industrial scale by isotope separation of the isotopes in the chromatograph column. The invention ensures more efficient and profitable (i.e. the lower expenditures and power consumption) separation of the isotopes.

EFFECT: the invention ensures more efficient and profitable with the lower expenditures and power consumption separation of the isotopes.
