Title: Isotopic separation of D sub 2 O from H sub 2 O using ruthenium adsorbent

Abstract

This paper describes a one-phase method for enriching the concentration of D{sub 2}O in solutions of D{sub 2}O and H{sub 2}O. It comprises: contacting in the absence of hydrogen gas steam phase D{sub 2}O and steam phase H{sub 2}O, with the hexagonal surface of crystalline ruthenium having a particle size greater than 10 nanometers so that sufficient (001) face is exposed to produce enriched D{sub 2}O. Also described is a one-phase method of enriching the concentration of D{sub 2}O and solutions of D{sub 2}O and H{sub 2}O. It comprises: contacting the D{sub 2}O and H{sub 2}O in the steam phase with the hexagonal surface of crystalline ruthenium wherein the ruthenium is divided into particles of about 1 micron to produce enriched D{sub 2}O.
