Publication number: 20130008855Abstract: A method for treating aqueous solutions, wherein a filtrate material is manufactured to have a polymer with ion exchange properties adhered to the surface or impregnated within a porous, granular particle such that the resultant structure does not result in any agglomeration or binding of the granular particles, thereby retaining the maximum surface area of the particle for reacting with metal impurities in solution. A filtrate material comprised of a porous granulated particle and an ion exchange polymer. A method of treating aqueous solutions by passing an aqueous solution through the filtrate material to remove metal impurities in the solution. A method of regenerating the filtrate material that is saturated with metal impurities.Type: ApplicationFiled: March 22, 2010Publication date: January 10, 2013Applicant: SURFATAS, LLCInventors: Kenn R. Vest, Arvind S. Patil

Patent number: 8349187Abstract: A method and solution for eluting one of antimony(V) and a mixture of antimony(III) and antimony(V) from an ion exchange resin, comprises contacting the resin with an eluting solution comprising thiourea having a concentration of at least 0.002 M and hydrochloric acid having a concentration of at least 3 M. The method can be used for electrolytes in an industrial electrorefining process, by the further steps of contacting the electrolyte with an ion exchange resin to adsorb the antimony from the electrolyte and separating the resin from the electrolyte, before contacting the resin with the eluting solution comprising thiourea and hydrochloric acid. The method and solution address the difficulties of removing antimony(V), and allow for increased reuse of the resins.Type: GrantFiled: December 8, 2009Date of Patent: January 8, 2013Assignee: Her Majesty the Queen in Right of Canada as Represented by the Minister of Natural ResourcesInventor: Patricio A.

Publication number: 20130001167Abstract: A method is described for removing hard water components from water wherein the removed ions are not replaced by sodium ions. The method includes the steps of passing water having dissolved hard water components through a water-softening column containing a tungsten-based sorbent. The hard water components are reacted with tungsten based sorbent to remove the hard water components. The tungsten based sorbent is regenerated for later use in the step of reacting. The resulting by-products include calcium and magnesium or ammonium nitrate, all of which may be sold and used for various purposes.Type: ApplicationFiled: March 8, 2011Publication date: January 3, 2013Applicant: THE BOARD OF REGENTS FOR OKLAHOMA STATE UNIVERSITYInventor: Allen Wallace Apblett
