Abstract

Certain rare earths possessing high thermal neutron absorption cross sections, when present in only trace quantities in metals used in nuclear technology, must be separated before a satisfactory spectrographic determination can be made. These rare earths are separated from beryllium and magnesium by precipitation as oxalates with added thorium as a carrier. The thorium is removed by an 8-quinolinol extraction leaving a residue suitable for spectrographic analysis. With zirconium, titanium, uranium, and stainless steel, a preliminary fluoride precipitation is made. At least 96% of the rare earths are consistently recovered.

ION EXCHANGE SEPARATION AND SPECTROGRAPHIC DETERMINATION OF SOME RARE EARTHS IN BERYLLIUM, URANIUM, ZIRCONIUM, AND TITANIUM METALS, ALLOYS, AND OXIDES. COLLECTION WITH CALCIUM AND MAGNESIUM FLUORIDE AND ION EXCHANGE SEPARATION

Journal Article Kallmann, S ; Oberthin, H K ; Hibbits, J O - Analytical Chemistry (U.S.) Formerly Ind. Eng. Chem., Anal. Ed.

Yttrium, precipitated as the fluoride through coprecipitation of Ca plus MgF, quantitatively collects the fluorides of Eu, Dy, Gd, and Sra, even in the presence of large amounts of U, Be, Ti, or Zr. The filtered and ignited fluoride mixture is converted to sulfates and the Ca and Mg plus residual matrix elements are removed by ion exchange. Yttrium is recovered as oxalate prior to subjecting it and tbe coprecipiated rare earth to spectrographic analysis. (auth)

SEPARATION OF THORIUM FROM RARE EARTHS, ZIRCONIUM, AND OTHER ELEMENTS BY CATION EXCHANGE CHROMATOGRAPHY

Journal Article Strelow, F W.E. - Analytical Chemistry (U.S.) Formerly Ind. Eng. Chem., Anal. Ed.

Thorium has a high affinity for the Dowex 50 cation exchange resin and it is not eluled tom a column of the resin even by relatively concentrated hydriochloric acid. Semiquantitative affinities for AG 50 resins in hydrochloric acid were investigated for 23 cations, and ''single element'' elution curves were prepared for those with high affinities. A method was developed a separate thorium quantitatively, even in small amounts. from zirconium and the rare earths.

THE DETERMINATION OF THORIUM ALPHA-ACTIVITY AND OF ZIRCONIUM, CERIUM AND RARE EARTH BETA-ACTIVITIES IN SOLUTIONS CONTAINING ALUMINIUM

Technical Report Wallace, C G

Aluminium is removed as soluble alunninate with sodium hydroxide solution. Thorium is co-precipitated with zirconium iodate and subsequently separated from the latter in fluoride solution. Zirconium, after hydrolysis of its fluoride complex with sodium hydroxide, is precipitated as the mandelate. Cerium and the rare earths are separated in iodate solution and are finally precipitated as oxalates. (auth)
Separation and Spectrographic Determination of Rare Earths in Uranium; SEPARACAO E DETERMINACAO ESPECTROGRAFICA DE TERRAS RARAS EM URANIO

Technical Report Abrao, A

Traces of rare earths elements, mainly those possessing high thermal neutron absorption cross sections: Gd, Dy, Er, Sm, and Eu, were determined spectrographically after chemical separation from uranium. Uranyl chloride in hydrochloric acid was extracted with TBP, the rare earths were coprecipitated with thorium ammonium fluoride, Th was removed with 8-quinolinol in chloroform, and the rare earths coprecipitated with spectrographic pure lanthanum hydroxide. The oxides were diluted with spec pure graphite and burned in a d-c arc. (auth)
PHOTOMETRIC DETERMINATION OF RARE EARTHS IN ORES WITH ARSENAZO III (in Russian)

Journal Article Goryushina, V G ; Savvin, S B ; Romanova, E V - Zh. Analit. Khim.

The photometric method with the use of arsenazo III is the most sensitive and selective for the determination of rare earths. Down to mu g of rare earths in 50 ml at pH 1.8 can be determined by adding 2 ml of a 0.1% arsenazo III solution in the presence of 5 mg of aluminium masked with sulfosalicylic acid and of 0.5 mg of zirconium masked with oxalic acid. Iron reduced with hydroxylamine hydrochloride in amounts of 5 mg does not interfere. Many other elements including magnesium, barium, copper, nickel, manganese, chromium, tin, and titanium do not interfere in amountsmore »« less
