In the present paper a procedure is described for the separation of micro quantities of gadolinium from other natural uranium fission product rare earths. The literature already contains separation procedures for all these elements, though often of rather limited scope, because the main aim has been to separate the major rare earth constituents of 2asU by: 1.   (). Molecular modeling guided isotope separation of gadolinium with strong cation exchange resin using displacement chromatography. Separation Science and Technology: Vol. 52, No. 14, pp. Cited by: 3. The extraction behavior of commonly associated metals with gadolinium was studied as a function of phosphoric acid concentration. Tulsion CH resin showed selective extraction towards heavy rare earths (Lu and Yb) which could be separated from other rare earths at 3 mol/L H 3 PO 4, similar to wet phosphoric acid (3–5 mol/L). Samarium and gadolinium are used in several applications: nuclear industry, lasers, supermagnets among others. This paper presents a technological contribution to the study of RE separation, in order to obtain Sm and Gd concentrated solutions. Experiments were carried out on a laboratory scale using solvent extraction techniques.

The separation of gadolinium from other rare earths with similar chemical properties has been successfully accomplished by adopting a dual cycle solvent .

Soc. , 78, 10, –   Gadolinium is special among the rare-earth ions as it has high value of spin moment (7 Bohr magnetron) without having any orbital moment. The spin-vortex formation in Gadolinium Stearate (GdSt) LB films have been shown by a series of magnetization and polarized neutron reflectivity measurements [15], [18], [23].   Progress in the Separation Processes for Rare Earth Resources. ,,, DOI: /B Raju Banda, Ho Seok Jeon, Man Seung Lee.

The separation of this group into individual elements is usually undertaken by the reduction of Eu(III) to Eu(II) and its precipitation as EuSO 4 (Morais and Ciminelli, , Morais and Ciminelli, , Morais and Ciminelli, , Preston et al., ), followed by Sm.
