Abstract
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 poreswhile supplying 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 waterfrom the water vapor not adsorbed on the adsorbent; and then recovering deuterium-depleted water containing a large amount of light waterfrom the water vapor adsorbed on the adsorbent.
