Process for removal of ammonia and acid gases from contaminated waters

Patent King, C Judson [Kensington, CA]; MacKenzie, Patricia D [Berkeley, CA]

Contaminating basic gases, i.e., ammonia, and acid gases, e.g., carbon dioxide, are removed from process waters or waste waters in a combined extraction and stripping process. Ammonia in the form of ammonium ion is extracted by an immiscible organic phase comprising a liquid cation exchange component, especially an organic phosphoric acid derivative, and preferably di-2-ethyl hexyl phosphoric acid, dissolved in an alkyl hydrocarbon, aryl hydrocarbon, higher alcohol, oxygenated hydrocarbon, halogenated hydrocarbon, and mixtures thereof. Concurrently, the acidic gaseous contaminants are stripped from the process or waste waters by stripping with steam, air, nitrogen, or the like. The liquid cation exchangemore »« less

Method for removal of plutonium impurity from americium oxides and fluorides

Patent FitzPatrick, John R [Los Alamos, NM]; Dunn, Jerry G [Los Alamos, NM]; Avens, Larry R [Los Alamos, NM]

Method for removal of plutonium impurity from americium oxides and fluorides. AmF.sub.4 is not further oxidized to AmF.sub.6 by the application of O.sub.2 F at room temperature, while plutonium compounds present in the americium sample are fluorinated to volatile PuF.sub.6, which can readily be separated therefrom, leaving the purified americium oxides and/or fluorides as the solid tetrafluoride.

Method of removing arsenic and other anionic contaminants from contaminated water using enhanced coagulation

Patent Teter, David M.; Brady, Patrick V.; Krumhansl, James L.; ...

An improved water decontamination process comprising contacting water containing anionic contaminants with an enhanced coagulant to form an enhanced floc, which more efficiently binds anionic species (e.g., arsenate, arsenite, chromate, fluoride, selenate, and borate, and combinations thereof) predominantly through the formation of surface complexes. The enhanced coagulant comprises a trivalent metal cation coagulant (e.g., ferric chloride or aluminum sulfate) mixed with a divalent metal cation modifier (e.g., copper sulfate or zinc sulfate).

Method of improving fuel cell performance by removing at least one metal oxide contaminant from a fuel cell electrode

Patent Kim, Yu Seung [Los Alamos, NM]; Choi, Jong-Ho [Los Alamos, NM]; Zelenay, Piotr [Los Alamos, NM]

A method of removing contaminants from a fuel cell catalyst electrode. The method includes providing a getter electrode and a fuel cell catalyst electrode having at least one contaminant to a bath and applying a voltage sufficient to drive the contaminant from the fuel cell catalyst electrode to the getter electrode. Methods of removing contaminants from a membrane electrode assembly of a fuel cell and of improving performance of a fuel cell are also provided.

Method for removing contaminants from plastic resin

Patent Bohnert, George W [Harrisonville, MO]; Hand, Thomas E [Lee's Summit, MO]; DeLaurentiis, Gary M [Jamestown, CA]

A method for removing contaminants from synthetic resin material containers using a first organic solvent system and a second carbon dioxide system. The organic solvent is utilized for removing the contaminants from the synthetic resin material and the carbon dioxide is used to separate any residual organic solvent from the synthetic resin material.
