Question

Which reagent used for solvent extraction method for separation of lanthanide?

Answer 1

Answer:

investigate the synergistic solvent extraction of the metals of the lanthanoid series (La, Nd, Eu, Ho, and Lu) with a mixture of the chelating extractant 1-(2-thienyl)-4,4,4-trifluoro-1,3-butanedione (HTTA) or 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-on (HP) and PAR in CHCl3.

Answer 2

The reagent used for the solvent extraction method for the separation of lanthanide is a mixture of Cyanex 272 and caprylic acid

Explanation:

• The solvent extraction method is the extraction technique that is used to extract the lanthanide (III) from the acetate solutions.
• Here the solution of the ions is contacted into an ion exchange resin which results in an equilibrium between the resin and solution.
• Here separation of the different ions is done by the distribution of the various ions in between the solid and liquid phases.
• Here the differences are increased by selectively complexing the ions and then repeating the ion-exchange reaction several times in the solution.
• n this the lanthanides mainly the oxides can be converted to fluorides or chlorides which are later reduced with calcium to metallic form.
