Method to separate isotopes

Creators

Description

An extraction by means of supercritical pure gases (e.g. CD2) or gas mixtures is proposed to separate isotopes, especially H/D, Li-6/Li-7, and U-235/U-238, and water or benzol is used as entrainer. The extraction shall be carried out at pressures of about 350 bar above the critical pressure with the temperature being by up to 100 deg C above the critical temperature. A NaCl-solution and the change of the isotopic ratio Cl-35/Cl-37 are investigated for example purpose. (orig./PW)
