Patent number: 7807058Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.Type: GrantFiled: August 7, 2009Date of Patent: October 5, 2010Assignee: J.I.

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: September 13, 2006Date of Patent: February 16, 2010Assignee: George Mason Intellectual Properties, Inc.Inventors: Mark P. S. Krekeler, Stephen C. Elmore, Cynthia M. Tselepis, Danielle Stoll

Publication number: 20100028505Abstract: The present invention relates to liquid clarification. More closely, the invention relates to beverage clarification, such as reduction of colloidal (not microbial) haze-causing substances in beer or related beverages such as wine, juices, flavorings etc. The method of the invention uses a hydrophilic surface for adsorption of haze-forming substances by hydrogen bonding interaction properties between the surface and the haze-forming substances.Type: ApplicationFiled: January 28, 2008Publication date: February 4, 2010Applicant: GE HEALTHCARE BIO-SCIENCES ABInventors: Michael Katzke, Ola Lind, Tobias Soderman, James Van Alstine

Patent number: 7655097Abstract: In the washing process of the invention, the solid particles in a high-concentration zone, which is formed in a washing tank by a gravitational sedimentation of solid particles, are continuously washed by a counter-current contact with upward flow of a washing liquid which is fed from the bottom portion of the washing tank. With this process, the impurities in the solid particles are sufficiently removed by a simple apparatus. Since the used washing liquid can be recycled as the disperse medium for feeding the solid particles and as the washing liquid, the amount of used washing liquid to be discharged as the waste from the system is reduced.Type: GrantFiled: September 30, 2004Date of Patent: February 2, 2010Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Hideaki Fujita, Hiroshi Machida, Nobuo Namiki, Yoshio Waguri

Publication number: 20100012587Abstract: The invention concerns a method for treating a fluid. According to the invention, the fluid is contacted with a substrate at the surface of which there is a network of organic molecules, hereafter referred to as “network molecules”, having a central corre and at least one lateral arm, said molecules being adsorbed at the surface of the substrate. The invention also concerns a two-dimensional molecular sieve consisting of substrate at the surface of which a network of network molecules is adsorbed. The invention further concerns a module for treating a fluid comprising means for circulating the fluid to be treated and containing one or more two-dimensional molecule sieves.Type: ApplicationFiled: March 29, 2007Publication date: January 21, 2010Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUEInventors: Andre-Jean Attias, Fabrice Charra, Ludovic Douillard, Celine Fiorini, David Kreher, Fabrice Mathevet, Guillaume Schull

Patent number: 7641800Abstract: A process for the removal of liquid, gaseous and/or dissolved constituents from a process stream. The process stream is contacted with an adsorbent comprising a first porous material which has been incorporated into a second porous material at least 30 vol. % of the pores of the first and second porous materials of which are filled with an extraction liquid. The affinity between the adsorbent and the constituents to be removed exceeds the affinity between the constituents and the extraction liquid.Type: GrantFiled: June 24, 2005Date of Patent: January 5, 2010Assignee: OTV S.A.Inventors: Cornelis Johannes Govardus van Strien, Elwin Schomaker

Publication number: 20090314719Abstract: The invention relates to metal-treated particles, methods for their preparation and methods for using metal-treated particles for, e.g., remediation of process waste-water, sewage, contaminated groundwater aquifers, and soil containing harmful contaminants. Another aspect of the invention relates to a metal-treated particle comprising a ferrosoferric oxide core and a metal supported on the core, where the average diameter or other largest transverse dimension of the core is from about 75 nm to about 990 nm and the amount of metal supported on the core is from about 8% to about 22% by weight, based on the weight of the metal-treated particle.Type: ApplicationFiled: August 20, 2009Publication date: December 24, 2009Inventor: Peter Papagianakis
