Physicochemical conversion of human exometabolites for the NaCl involvement into the mass exchange in closed life support systems

Аннотация

The results of the original physicochemical method of NaCl recovery out of the mineralized human metabolites’ solution obtained after their oxidation in H₂O₂ aqueous solution under the influence of alternating electric current are presented. The technological stages of the newly developed method are described, and its efficiency at each stage is demonstrated. The possibility to efficiency isolate Na from the NaHCO₃ solution by applying electrodialysis technology and temperature separation is demonstrated. The HCl synthesis from Cl₂ and H₂ released during electrolysis is stable, allowing its combining with electrodialysis aimed at NaCl production under the conditions of a closed life support system.
