Abstract
The invention relates to physical chemistry, in particular, to a method for separating the radioactive hydrogen isotope - tritium in the aqueous phase, using a separation system that includes a combination of a proton exchange membrane electrolysis cell and a fuel cell. The proton exchange membrane material of the electrolysis cell includes sulfonated poly(etheretherketone) (SPEEK) with an integrated graphene layer to increase the tritium separation coefficient using quantum sieving. The proposed method provides for selective separation of tritium water from a common water reservoir, concentration of the separated tritium in a smaller volume in the aqueous phase and it can be used for isolating tritium from radioactive zones under extreme conditions. The invention opens up new opportunities to regenerate tritium in the aqueous phase, increase the tritium activity for secondary use in the nuclear energy industry.
