摘要:
A mark transfer tool utilizing a coat film transfer technology, concerning various marks composed of characters, codes, patterns or their combination. A mark transfer tape (T) has multiple pressure-sensitive adhesive transfer marks (M) adhered and held at specified intervals peelably on the surface of a base tape (15), and the transfer marks (M) are prepared as adhesive seals of which adhesive force of the back-side pressure sensitive adhesive layer (19) adhered to the transfer area is set larger than the adhesive holding force on the base tape (15). Like adhesive seals, the transfer marks (M) once transferred on the transfer area can be once peeled off and adhered again, or peeled and removed when no longer needed.

摘要:
A method of oxidatively decomposing a radioactive ion-exchange resin is described, the method comprising oxidatively decomposing a radioactive ion-exchange resin containing an anion-exchange resin with hydrogen peroxide used as an oxidizing agent in the presence of iron and copper ions used as catalysts, wherein the weight ratio of hydrogen peroxide to the ion-exchange resin, that is the ratio of the net weight of hydrogen peroxide to the dry weight of the ion-exchange resin containing an anion-exchange resin, is held to be no higher than 17 and the pH of the reaction system is adjusted to be within the range of 0.5 to 6, or citric acid ions are preliminarily adsorbed on the radioactive ion-exchange resin before it is subjected to decomposition treatment or citric acid ions coexist with the radioactive ion-exchange resin in the oxidatively decomposing system, and an apparatus used for conducting the method is also described.
摘要:
A process for the treatment of water with ozone in which trace amounts of organic substances contained in water to be treated are oxidized and decomposed by diffusing ozone into the water introduced into a reaction tank, by injecting a chelate compound into the water to be treated after or just before the introduction of the water into the reaction tank. Preferred chelate compounds include ethylenediaminetetraacetic acid disodium salt, ethylenediaminetetraacetic acid calcium salt, ethylenediaminetetraacetic acid magnesium salt, ethylenediaminetetraacetic acid iron salt and iron citrate.
