“…Preliminary studies showed that metals in the sulfate systems (e.g., PEO 1500-Na 2 SO 4 -H 2 O) could not be extracted due to the formation of strong high-charge [Me(SO 4 ) x ] y− type acid complexes which are not extracted by water-soluble polymers [17,22,29]. The anionic sulphates [Me(SO 4 ) x ] y− formed from the metal ion with a high negative hydration Gibbs energy (Δ G hyd ) and the anion with a strong salting-out effect (ΔGhyd(SO42−)=−1145 kJ/mol) [30] have a lower affinity for the PEO-rich phase of the extraction system.…”

This article presents an ecologically safe aqueous two-phase system based on poly(ethylene oxide) with a molecular weight of 1500, designed for complex extraction of Ni(II), Co(II), Fe(III), Mn(II), Zn(II), Cu(II), and Al(III) from nitrate solutions. A kinetic dependence has been investigated for a distribution ratio for the metals examined. The influence of pH-values, temperature, initial metal concentration, and nitric acid content have on the extraction of a wide range of metals in the heterogeneous poly(ethylene oxide) 1500-NaNO3-H2O system has been discovered. As a result, the complex extraction of metals (EMe > 60%) was achieved in one step of extraction without introducing additional chemicals into the system.

“…Equations (11) and (14) describe the elution profiles of the compound K Dj (j = 1,2,3) corresponding to the second X n,1 and third X n,2 sample injections. Equations (11), (12), (14) and (15) can be obtained by putting r = 1 and r = 2 in Equations (6) and 9, respectively. The resulting concentration profiles after two and three sample injections are described by the equations:…”

Countercurrent liquid-liquid chromatographic techniques (CCC), similar to solvent extraction, are based on the different distribution of compounds between two immiscible liquids and have been most widely used in natural product separations. Due to its high load capacity, low solvent consumption, the diversity of separation methods, and easy scale-up, CCC provides an attractive tool to obtain pure compounds in the analytical, preparative, and industrial-scale separations. This review focuses on the steady-state and non-steady-state CCC separations ranging from conventional CCC to more novel methods such as different modifications of dual mode, closed-loop recycling, and closed-loop recycling dual modes. The design and modeling of various embodiments of CCC separation processes have been described.

The non-linear equation of the radial oscillations of a liquid ball in an immiscible liquid under the exposure of time-varying sound pressure was obtained. The behavioral features of a liquid spherical drop placed in such a media were analyzed in the presence of ultrasound irradiations. The slowing-down effect of the extracted metal ions under its exposure has been studied for the first time, using theoretical and experimental approaches. This phenomenon mechanism was revealed, and analytical equations for the mass transfer rate as a function of the sound pressure oscillations amplitude and the substrate ultrasonic treatment time are presented. Experimental studies of Fe3+ ions extracted from chloride and nitrate solutions in systems based on water-soluble polymers were carried out, and a convincing coincidence with the results of theoretical calculations was established. The conditions for achieving the desired extraction efficiency when applying the ultrasonic stimulating effect are specified. The derived result opens the complementary possibility in operations, with the separateness of extraction processes, that which has the essential practical importance.
