摘要： Water is separated into deuterium-depleted water having a low deuterium concentration and deuterium-enriched water having a high deuterium concentration easily and at low cost.
A method for separating water into deuterium-depleted water and deuterium-enriched water, the method including: adsorbing water vapor on an adsorbent including a pore body having pores 6 while suppling water vapor to and allowing the water vapor to pass through the adsorbent for a predetermined period of time; recovering deuterium-enriched water containing a large amount of heavy water 8 from the water vapor not adsorbed on the adsorbent; and then recovering deuterium-depleted water containing a large amount of light water 7 from the water vapor adsorbed on the adsorbent.

摘要： Deuterium-depleted water is produced easily and inexpensively.
A method for producing deuterium-depleted water by removing heavy water and semi-heavy water from water includes an adsorption step of supplying water vapor to a predetermined adsorbent at pressure at which heavy water and semi-heavy water are adsorbed by the adsorbent and light water is not easily adsorbed, causing the heavy water and semi-heavy water to be adsorbed, and recovering the water vapor not adsorbed by the adsorbent. The method also includes a desorption step of maintaining vapor pressure around the predetermined adsorbent which has adsorbed the water vapor in a range in which light water is desorbed and heavy water or semi-heavy water is not easily desorbed, and recovering the water vapor desorbed from the adsorbent.
