Permeation process of the cobalt(II) (Co) complexes of the hydroxyoxime extractant, LIX63 and/or of the carboxylic acid extractant, Versatic Acid 10 (VA10), through the interface between cyclohexane and water layers was investigated using a hybrid Monte Carlo/Molecular Dynamics (MC/MD) method where MC and MD were performed for coordination reactions probabilistically and molecule movements on short time scale, respectively. For VA10 system, no Co 2+ permeated through the interface and this suggests that VA10 are not coordinated directly to Co 2+ . For Co complexes with LIX63, two LIX63 molecules were coordinated with Co 2+ from the organic phase. The complexes rotated and one of the LIX63 molecules was located between Co 2+ and the aqueous phase, then the complexes migrated into the organic phase. This suggests that the diffusion of the extractant molecules and the rotation of the complexes around the interface are important for solvent extraction.

The solubilities of palladium(II) -diketonates (PdL2, L = acetylacetonate (acac), trifluoroacetylacetonate (tfa), and thenoyltrifluoroacetonate (tta)) in supercritical carbon dioxide (SC-CO2) from 318 – 338 K and 8 – 25 MPa were investigated by UV-vis spectrophotometer equipped with a high-pressure optical cell. The molar absorptivities for Pd(acac)2, Pd(tfa)2, and Pd(tta)2 in SC-CO2 were estimated as 1.14 104 M-1 cm-1 at 324 nm, 8.16 103 M-1 cm-1 at 336.5 nm, and 2.70 104 M-1 cm-1 at 322.5 nm, respectively. Solubilities in SC-CO2 increase in order of Pd(tta)2 < Pd(acac)2 < Pd(tfa)2, i.e., 6.5 10-6 < 5.2 10-5 < 1.3 10-4 M at 318 K and 11.5 MPa. The experimental solubilities were correlated using the equation proposed by Chrastil and the thermodynamic parameters for each PdL2 were estimated.
