文摘

A study of the utilization of aqueous decomposition of sodium amalgam for the production ofdeuterium-depleted water is presented. In the framework of this work the correlation betweenthe deuterium content of the hydrogen gas and the concentration of the aqueous alkali, bothformed in the reaction of sodium amalgam with water, is established. The sodium amalgam isprepared via sodium chloride electrolysis. In addition to the formation of an industrial alkalinesolution containing 50% w/w sodium hydroxide, hydrogen gas with a deuterium concentrationof 50 ppm is obtained. This hydrogen gas is suitable (e.g., via combustion) for the preparationof deuterium-depleted water used, e.g., in cancer therapy.
