Method for producing deuterium-reduced water and method for producing deuterium-concentrated water

摘要

Separating water into deuterium-reduced water and deuterium-enriched water easily and at low cost. A method for producing deuterium-reduced water by removing heavy water and semi-heavy water from water, wherein one or more metals selected from Group 8 to Group 13 of the Periodic Table of Elements are added to the carbon material as an additive metal. The adsorbent 11 is adsorbed while being supplied with water vapor for a predetermined time, and then brought into contact with light hydrogen gas, and then the water vapor adsorbed on the adsorbent 11 is desorbed and recovered. It is characterized by that.
