摘要： PURPOSE:To improve separation efficiency by using diethylene glycol monomethyl ether as an exchanging liq. in the process in which hydrogen atom of a working material is exchanged with hydrogen isotope of starting water, the working material is dissociated by laser irradiation, the dissociated product containing hydrogen isotope is separated and recovered. CONSTITUTION:In isotope exchanging reaction stage, the exchanging liq. dissolving the working material is brought into contact with the steam of starting water in the presence of an alkaline catalyst, hydrogen atom of the working material is exchanged with hydrogen isotope of starting water, then the exchanging liq. containing the working material is brought into contact with gaseous working material, and the gaseous working material is allowed to dissolve in the exchanging liq., and the working material after exchanging reaction is transferred to gas phase. In dissociation stage, gaseous working material containing hydrogen isotope is dissociated selectively by laser irradiation. In recovering stage of the material containing dissociated hydrogen isotope and in isotope exchanging reaction stage, diethylene glycol monomethyl ether is used as the exchanging liq.

摘要： PURPOSE:To efficiently concentrate the isotopes of nitrogen and oxygen by joining a concentrating process of the isotopes of nitrogen and oxygen dependent on the low-temp. distillation method of nitrogen monoxide to a concentrating process of the isotope of nitrogen dependent on an NO-HNO3 exchange method. CONSTITUTION:When regulated nitric acid is supplied at constant flow rate to an NO-HNO3 exchange tower 10 from the top thereof, nitric acid reached the bottom of the tower is supplied to a reflux tower. It is allowed to react with nitrous gas and changed into nitrogen monoxide and sulfuric acid. Further in an exchange tower 10, the exchange reaction of the isotope of nitrogen is caused by nitrogen monoxide and nitric acid and N is concentrated in nitric acid. On the other hand, high-grade nitrogen oxide is contained in gaseous nitrogen monoxide discharged from the top of the tower. High-purity gaseous nitrogen monoxide is obtained in an NO purifier 20. Thereafter N, O and O are concentrated in an NO distillation tower and N, O are recovered in the bottom of the tower. 170 is recovered in the intermediate part thereof and N, O are recovered in the top of the tower. In such a way, the isotopes of nitrogen and oxygen can be efficiently concentrated.

摘要： PURPOSE:To produce catalysts having effective large specific surface area and favorable water repellence, for use in the enrichment of hydrogen isotopes by water-hydrogen exchange reaction, by allowing a catalystic substance of a metal of Gp. VIII to be supported on a porous carrier of three-dimensional irregular netlike structure consisting of water-repellent material (e.g. fluororesin) or coated with the above material on the surface.
