Liquid-liquid solvent extraction of rare earths from chloride medium with sec-nonylphenoxy acetic acid and its mixtures with neutral organophosphorus extractants

In the present study, sec-nonylphenoxy acetic acid (CA100) and its mixtures with four neutral organophosphorus extractants, tri-butyl-phosphate (TBP), 2-ethylhexyl phosphonic acid di-2-ethyl ester (DEHEHP), Cyanex923, and Cyanex925 have been applied to the extraction of rare earths. Results show that all the four mixing systems do not have evident synergistic effects on the extraction of rare earths. The different extraction effects have been considered to the separation of rare earths. The four mixtures may be applied to the separation of yttrium from some certain lanthanoids at proper mole fractions of CA100. Pleiades Publishing, Ltd., 2011.

Effect of the 18-crown-6 and benzo-18-crown-6 on the solvent extraction and separation of lanthanide(III) ions with 8-hydroxyquinoline

The synergistic solvent extraction of 13 lanthanides with mixtures of 8-hydroxyquinoline (HQ) and the crown ethers (S) 18-crown-6 (18C6) or benzo-18-crown-6 (B18C6) in 1,2-dichloroethane has been studied. The composition of the extracted species has been

Acid Solvolysis Kinetics of Lanthanide Porphyrins

The kinetics of the acid solvolysis reactions of twelve water-soluble lanthanide tetrakis(N-methyl-4-pyridyl)porphyrins (Ln-P) follow rate = k1+>2/ (k-1/k2) + +>> at 25 deg C, I = 0.8M (LiNO3/HNO3) indicating that two protons are required for solvolysis, and since log (k1k2/k-1) = 45.0R0 - 39.4 (R0 is the ionic radius in Angstroem), a 0.1 Angstroem change in radius has a 32000 fold rate effect.
