Title ADSORBENT FOR HEAVY WATER ADSORPTION AND METHOD FOR SEPARATING HEAVY WATER NEW_EN
Abstract An adsorbent for heavy water adsorption, which selectively adsorbs heavy water, and which contains an amylose.
Outline of related art and contending technology BACKGROUND ART
From the conventional, 1H and 16O of light and composed of, other than hydrogen isotope other than 16O and 1H isotopes of oxygen and having at least one heavy, various methods of separating has been studied (see Non-Patent Document 1). Patent Document 1 is, by the centrifugal separation treatment of the water vapor, water vapor from the tritium water has been disclosed another method. In addition, in Patent Document 2, the injection of the liquid droplets can be classified, a method of separating the water isotopes have been disclosed.
