Publication number: 20140205052Abstract: A chemical decontamination reagent containing a reducing agent, a reductive metal ion, and an inorganic acid is provided to remove a radioactive oxide layer on a metal surface. The reagent can dissolve the radioactive oxide layer on the metal surface effectively at a relatively low temperature and enables a simple process of contacting the reagent to the radioactive oxide, thus economically effective in terms of cost and time required for the process. Since the decontamination does not use a conventional organic chelating agent such as oxalic acid, but the reducing agent as a main substance, the residuals of the reducing agent remained after decontamination can be decomposed and removed with an oxidizing agent. Due to the easy decomposition with the chemical decontamination reagent, secondary wastes can be minimized and the radionuclides remained in the decontamination reagent solution can be removed effectively.Type: ApplicationFiled: September 4, 2013Publication date: July 24, 2014Applicants: Korea Hydro And Nuclear Power Co., Ltd., Korea Atomic Energy Research InstituteInventors: Hui-Jun Won, Chong-Hun Jung, Sang Yoon Park, Wangkyu Choi, Jung-Sun Park, Jeikwon Moon, In-Ho Yoon, Byung-Seon Choi

Patent number: 7429556Abstract: The disclosed invention is a method for the production of a universal decontaminant solution comprised of at least one oxidant and halide salt for neutralizing chemical toxicants that include organosulfur and organophosphorus-containing compounds, such as those found as pesticides, herbicides, or chemical warfare agents, as well as providing disinfection capability against viruses, bacteria, spores, fungi, toxins, and those classified as biological warfare agents. The overall generation and application of the decontaminant solution creates an unexpected synergistic effect toward rates of detoxification, whereas in most cases where the same oxidants were used individually, the same result would not be achieved. A method for the in situ generation of hypochlorous acid and hypochlorite by a monopersulfate compound and alkali metal chloride salt is also described.Type: GrantFiled: October 23, 2003Date of Patent: September 30, 2008Assignee: Applied Research Associates, Inc.Inventors: Carrie Delcomyn, Michael Henley

Publication number: 20080228022Abstract: The present invention relates to a vacuumable gel that can be used for decontaminating surfaces, and also to the use of this gel. The decontamination may be, for example, a radioactive decontamination. The gel of the present invention is composed of a colloidal solution. It comprises from 5 to 25 wt % of an inorganic viscosity modifier relative to the total weight of the gel; from 0.01 to 0.2 wt % of a surfactant relative to the total weight of the gel, and, particularly preferably, a surfactant in an amount strictly below 0.1 wt % relative to the total weight of the gel; from 0.5 to 7 mol, per litre of gel, of an inorganic acid or base; and optionally from 0.05 to 1 mol, per litre of gel, of an oxidizer having a standard redox potential E0 greater than 1.4 V in a strong acid medium or of the reduced form of this oxidizer; the remainder being water. It may be applied, by spraying, to a surface to be decontaminated, and removed in the form of dry residues by suction or brushing after drying.Type: ApplicationFiled: October 3, 2006Publication date: September 18, 2008Applicants: COMMISSARIAT A L'ENERGIE ATOMIQUE, AREVA NCInventors: Sylvain Faure, Paul Fuentes, Yvan Lallot

Patent number: 7390432Abstract: An enhanced formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The enhanced formulation according to the present invention is non-toxic and non-corrosive and can be delivered by a variety of means and in different phases. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a bleaching activator and water.Type: GrantFiled: September 20, 2002Date of Patent: June 24, 2008Assignee: Sandia CorporationInventor: Mark D. Tucker

Patent number: 7371714Abstract: A composition and methods of use for the decontamination of chemical agents, including chemical warfare agents. The decontamination composition is nontoxic, nonflammable and non-corrosive and includes an effective amount of a perfluorinated alkyl bromide or reactive perfluorinated alkyl bromide. The decontamination composition may include an oxidizer and a solvent.Type: GrantFiled: June 22, 2006Date of Patent: May 13, 2008Assignee: The United States of America as represented by the Secretary of the ArmyInventors: David S. Johnston, Gennady E. Platoff, Steven I. Baskin, Thomas P. Logan

Patent number: 7282470Abstract: A decontamination formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a bleaching activator, a sorbent additive, and water. The highly adsorbent, water-soluble sorbent additive (e.g., sorbitol or mannitol) is used to “dry out” one or more liquid ingredients, such as the liquid bleaching activator (e.g., propylene glycol diacetate or glycerol diacetate) and convert the activator into a dry, free-flowing powder that has an extended shelf life, and is more convenient to handle and mix in the field.Type: GrantFiled: July 18, 2003Date of Patent: October 16, 2007Assignee: Sandia CorporationInventors: Mark D.
