The present invention relates to a method for reducing the HTO concentration in a tritium-containing aqueous solution. The present invention includes bringing water vapor or the like of a tritium-containing aqueous solution into contact with a porous material having pores in a pore diameter range of 500 Å or less, selectively occluding the HTO in the tritium-containing aqueous solution in the porous material, and obtaining a tritium-containing aqueous solution in which the HTO concentration thereof is reduced. The present invention relates to a device used for reducing the HTO concentration in a tritium-containing aqueous solution. The present invention includes a reservoir for a raw tritium-containing aqueous solution, a means for generating water vapor or the like of the tritium-containing aqueous solution, an occlusion means in which is accommodated a porous material having pores in a pore diameter range of 500 Å or less, and a means for recovering the tritium-containing aqueous solution in which the HTO concentration is reduced. The present invention furthermore includes a transfer means for transferring the water vapor or the like to the occlusion means, and a means for transferring the tritium-containing aqueous solution in which the HTO concentration is reduced from the occlusion means to a recovery means.

[Problem] To provide a coating film capable of more reliably obtaining excellent water repellency and oil repellency. [Solution] The present invention pertains to a water- and oil-repellent coating film formed on the surface of a material in order to impart water repellency and oil repellency, the coating film being characterized in that (1) the coating film contains metal oxide composite particles, (2) the metal oxide composite particles contain a) metal oxide particles and b) a coating layer containing polyfluoroalkyl methacrylate resin formed on the surface thereof, and (3) the value obtained by dividing the fluorine content (wt%) of the metal oxide composite particles by the surface area (m2/g) of the metal oxide particles is 0.025 to 0.180.

A resin-coated metal pigment that is capable of simultaneous attainment of high water resistance of water base paint and chemical resistance of coating film; and a water base paint making use of the resin-coated metal pigment. There is provided a process for producing a resin-coated metal pigment, comprising the adsorption step of bringing a solution or dispersion of phosphoric ester component (A) into contact with a metal pigment to thereby prepare a phosphoric ester adsorbing metal pigment; the slurry preparation step of preparing a polymerization slurry having polymerization component (B) dissolved therein; and the coating step of polymerizing the polymerization component (B) so as to form a resin coating layer on the surface of the phosphoric ester adsorbing metal pigment. Further, there is provided a resin- coated metal pigment produced by the process, and provided a water base paint making use of the resin-coated metal pigment.
A method for producing a carbon-coated aluminum which enables adhesion between aluminum and an active material layer is disclosed. The carbon-coated aluminum having an aluminum (1) and a carbon-containing layer (2) formed over the surface of the aluminum (1) further comprises an intervenient layer (3) which is formed between the aluminum (1) and the carbon-containing layer (2) and contains aluminum element and carbon element. The method for producing such a carbon-coated aluminum comprises a step for placing an aluminum in a space where hydrocarbon-containing material is contained and a step for heating the aluminum placed in the space where hydrocarbon-containing material is contained.
