  • Method for producing deuterium depleted water, method for separating heavy water and light water, and method for producing deuterium concentrated water
    Patent number: 10471389
    Abstract: Utilizing the fact that a predetermined adsorbent adsorbs light water at an initial desorption rate higher than heavy water and semi-heavy water, deuterium depleted water having a reduced concentration of heavy water and semi-heavy water is produced easily and in a short time. A method for producing deuterium depleted water by removing heavy water and semi-heavy water from water, the method including: a desorption process in which a relative pressure around a predetermined adsorbent with adsorbed water vapor is reduced, and in which water vapor desorbed from the adsorbent is recovered during a period of time when a desorption rate of light water>a desorption rate of the heavy water and semi-heavy water.
