This mixture may form an aqueous clay suspension. The mixture can be refined by filtering to remove coarse material. The aqueous clay suspension may be applied to a radioactive material, allowing the radionuclides to be exchanged with cations in the aqueous clay suspension. The resulting aqueous slurry, a silver-based solution may be added to produce a suspension. The suspension may be collected, heated and analyzed.Type: GrantFiled: December 22, 2009Date of Patent: August 9, 2011Assignee: George Mason Intellectual Properties, Inc.Inventors: Stephen C. Elmore, Mark P. S. Krekeler, Danielle Stoll, Cynthia M. Tselepis

Publication number: 20110186520Abstract: A solid-phase extraction device utilizing a section of expanded polytetrafluoroethylene (ePTFE) tubing as the stationary phase is disclosed. The microscopic pores of ePTFE tubing are impregnated with a binding agent having an affinity for a target constituent within a matrix. The matrix is prepared and loaded onto the stationary phase of the system. The target constituent is retained by the stationary phase. The constituent is stripped from the stationary phase with a stripping solution, and collected for further analysis or use.Type: ApplicationFiled: April 7, 2011Publication date: August 4, 2011Applicant: DATACHEM LABORATORIES, INC.Inventors: Stephen M. Workman, Robert T. Shannon

Publication number: 20110100917Abstract: Provided is a method for recovering high-concentration and high-purity amine from amine-containing waste water generated from nuclear power plants and thermal power plants. The method includes: capturing amine and concentrating waste water using a cation exchange resin; separating amine from the concentrated amine-containing waste water; and carrying out further separation of amine via distillation. The method may be applied to treat amine, which causes an increase in biochemical oxygen demand (BOD) and total nitrogen concentration, drastically at the time of its generation from waste water of nuclear power plants and thermal power plants. In this manner, the method may prevent an increase in load of existing waste water treating plants and avoid a need for modifying the equipment in the existing plants.Type: ApplicationFiled: May 30, 2008Publication date: May 5, 2011Applicant: Soonchunhyang University Industry Academy Cooperation FoundationInventors: In Hyoung Rhee, Byung Gi Park, Hyun Jun Jung
