Other Related Research

Abstract

Bidentate organophosphorus compounds useful for extracting actinide elements from acidic nuclear waste solutions are purified of undesirable acidic impurities by contacting the compounds with ethylene glycol which preferentially extracts the impurities found in technical grade bidentate compounds.

Method for purifying bidentate organophosphorous compounds

Patent McIsaac, Lyle D.; Krupa, Joseph F.; Schroeder, Norman C.

Bidentate organophosphorous compounds are purified of undesirable impurities by contacting a solution of the compounds with a mercuric nitrate solution to form an insoluble mercuric bidentate compound which precipitates while the impurities remain in solution. The precipitate is washed and then contacted with a mixture of an aqueous solution of a strong mercuric ion complexing agent and an organic solvent to complex the mercuric ion away from the bidentate compound which then dissolves in the solvent. The purified bidentate compounds are useful for extracting the actinide elements from aqueous acidic nuclear waste solutions.

Method of purifying neutral organophosphorus extractants

Patent Horwitz, E Philip [Naperville, IL]; Gatrone, Ralph C [Naperville, IL]; Chiarizia, Renato [Rome, IT]

A method for removing acidic contaminants from neutral mono and bifunctional organophosphorous extractants by contacting the extractant with a macroporous cation exchange resin in the H.sup.+ state followed by contact with a macroporous anion exchange resin in the OH.sup.- state, whereupon the resins take up the acidic contaminants from the extractant, purifying the extractant and improving its extraction capability.

Bidentate organophosphorus solvent extraction process for actinide recovery and partition

Patent Schulz, Wallace W [Richland, WA]

A liquid-liquid extraction process for the recovery and partitioning of actinide values from acidic nuclear waste aqueous solutions, the actinide values including trivalent, tetravalent and hexavalent oxidation states is provided and includes the steps of contacting the aqueous solution with a bidentate organophosphorous extractant to extract essentially all of the actinide values into the organic phase. Thereafter the respective actinide fractions are selectively partitioned into separate aqueous solutions by contact with dilute nitric or nitric-hydrofluoric acid solutions. The hexavalent uranium is finally removed from the organic phase by contact with a dilute sodium carbonate solution.

Method for detecting organophosphorus compounds and illicit drugs

Patent Ewing, Robert G.; Valenzuela, Blandina R.; Atkinson, David A.

A method is disclosed for detecting organophosphorus compounds and illicit drugs using an ion detector. A vapor sample containing at least one analyte and at least one dopant is ionized. A proton-bound adduct ion is formed between the analyte and the dopant in a reaction region defined between the ionization source and the ion detector.
