Patent number: 9486799Abstract: Treatment of anion exchange materials containing hydroxyl containing moieties in the beta position relative to the quaternary center in the hydroxide form with glycidol substantially alters the selectivity of the anion exchange material. Furthermore, sequential treatments of first a hydroxide containing solution to put the anion exchange material in the hydroxide form followed by treatment with glycidol in an alternating sequence progressively changes selectivity in a predictable manner allowing facile manipulation of selectivity. Unique to the selectivities achievable with this chemistry is the ability to reverse the elution order of sulfate and carbonate. With all other known systems, carbonate elutes ahead of sulfate and sometimes compromises the ability to quantitate sulfate. With glycidol treatment, carbonate can be moved after sulfate which eliminates interference issues for samples containing significantly more carbonate than sulfate.Type: GrantFiled: September 11, 2012Date of Patent: November 8, 2016Assignee: DIONEX CORPORATIONInventor: Christopher A.

Patent number: 8937104Abstract: The cross-linked polyzwitterion/anion for the removal of strontium from aqueous solutions is a polyzwitterion having the following structure: and the corresponding anion formed by treating the polyzwitterion with a base, e.g., sodium hydroxide. The cross-linked polyzwitterion/anion (CPZA) was prepared using Butler's cyclopolymerization protocol. The CPZA resin was found to have a very good adsorption capacity for Sr2+ ions at low concentrations. The relatively strong rapid initial adsorption of 83% Sr2+ ions was followed by slower adsorption of the remaining 17%, which was described by an intraparticle diffusion model. The adsorption followed the Lagergren second-order kinetic model, and Temkin as well as Freundlich isotherm models. The negative ?Gs and ?H ensured the spontaneity and the exothermic nature of the adsorption process. The excellent adsorption and desorption efficiencies implied the efficacy of the resin in removing (as well as recovering) the metal ions from aqueous solution.Type: GrantFiled: April 29, 2013Date of Patent: January 20, 2015Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Shaikh Asrof Ali, Shamsuddeen Abdullahi Haladu
