20080234158 | Compositions counteracting pesticides and malodorants - This invention relates to compositions that counteract chemicals such as pesticides and malodorants. Also disclosed are a method for preparing such compositions and a method for applying such compositions to counteract pesticides or malordorants. | 09-25-2008 |
20100130398 | METHOD OF DECONTAMINATING A POROUS SURFACE CONTAMINATED WITH CESIUM - A method of decontaminating porous surfaces contaminated with water soluble radionuclides by contacting the contaminated porous surfaces with an ionic solution capable of solubilizing radionuclides present in the porous surfaces followed by contacting the solubilized radionuclides with a gel containing a radionuclide chelator to bind the radionuclides to the gel, and physically removing the gel from the porous surfaces. A dry mix is also disclosed of a cross-linked ionic polymer salt, a linear ionic polymer salt, a radionuclide chelator, and a gel formation controller present in the range of from 0% to about 40% by weight of the dry mix, wherein the ionic polymer salts are granular and the non cross-linked ionic polymer salt is present as a minor constituent. | 05-27-2010 |
20130072409 | SOLVENT COMPOSITION FOR REMOVING RADIOACTIVE SUBSTANCE AND REMOVING MATERIAL, AND METHOD FOR REMOVING RADIOACTIVE SUBSTANCE - The present invention relates to a solvent composition for removing radioactive substance, characterized by comprising at least one selected from hydrofluorocarbon, hydrofluoroether, and perfluoroketone as a medium for transporting the radioactive substance, and a method for removing a radioactive substance characterized by using the solvent composition for removing. | 03-21-2013 |
20130231270 | Superabsorbing Gel for Actinide, Lanthanide, and Fission Product Decontamination - The present invention provides an aqueous gel composition for removing actinide ions, lanthanide ions, fission product ions, or a combination thereof from a porous surface contaminated therewith. The composition comprises a polymer mixture comprising a gel forming cross-linked polymer and a linear polymer. The linear polymer is present at a concentration that is less than the concentration of the cross-linked polymer. The polymer mixture is at least about 95% hydrated with an aqueous solution comprising about 0.1 to about 3 percent by weight (wt %) of a multi-dentate organic acid chelating agent, and about 0.02 to about 0.4 molar (M) carbonate salt, to form a gel. When applied to a porous surface contaminated with actinide ions, lanthanide ions, and/or other fission product ions, the aqueous gel absorbs contaminating ions from the surface. | 09-05-2013 |
20150038387 | SUPERABSORBING GEL FOR ACTINIDE, LANTHANIDE, AND FISSION PRODUCT DECONTAMINATION - The present invention provides an aqueous gel composition for removing actinide ions, lanthanide ions, fission product ions, or a combination thereof from a porous surface contaminated therewith. The composition comprises a polymer mixture comprising a gel forming cross-linked polymer and a linear polymer. The linear polymer is present at a concentration that is less than the concentration of the cross-linked polymer. The polymer mixture is at least about 95% hydrated with an aqueous solution comprising about 0.1 to about 3 percent by weight (wt %) of a multi-dentate organic acid chelating agent, and about 0.02 to about 0.6 molar (M) carbonate salt, to form a gel. When applied to a porous surface contaminated with actinide ions, lanthanide ions, and/or other fission product ions, the aqueous gel absorbs contaminating ions from the surface. | 02-05-2015 |
20150361525 | METHOD OF MERCURY DECONTAMINATION - Methods of mercury decontamination are provided that include: contacting elemental mercury with a metal salt having a standard reduction potential sufficient to oxidize elemental mercury to an aqueous salt of mercury. In other aspects, methods of mercury decontamination are provided that include: contacting the metal surface with a solution comprising a metal salt having a standard reduction potential (E0) of greater than 0.85, thereby oxidizing a mercury contaminant to a soluble mercury salt. | 12-17-2015 |
