Solvent extraction is one of the most important techniques for separation and purification of rare earths. In practical industrial-scale process, however, group-separation of rare-earth ions by traditional organic- aqueous biphasic system have to be conducted by repeated liquid-liquid two phase equilibrating at carefully selected solution pH values. Repeated adjustments of solution pH value are always required to achieve separation of light, middle and heavy rare-earth ions. This work aims to solve purification of rare earths from aqueous solution containing non rare-earth impurities, such as Al(Ⅲ ), Fe(Ⅲ ), Si(Ⅳ), as well as one-step separation of multiple target rare-earth ions by a proposed novel strategy of three-liquid-phase extraction (TLPE). The three-liquid- phase system used for TLPE is composed of organic top phase, polymer-rich middle phase and salt-rich bottom phase. Experimental results indicate that co-existed non rare-earth impurities, Al(Ⅲ ), Fe(Ⅲ ) and Si(Ⅳ), can be selectively enriched into the top organic phase and polymer-rich middle phase of TLPS, respectively, while most of rare-earth ions remain in salt-rich bottom aqueous phase. And then, group separation of light, middle and heavy rare-earth ions, such as La(Ⅲ ), Eu(Ⅲ ) and Yb(Ⅲ ), respectively, into aqueous bottom phase, polymer middle phase and organic top phase can be achieved after removing impurities. The present works indicate that three-liquid-phase extraction is a promising separation method to treat the complex solution containing multiple rare earths and non rare-earth impurities.

Solvent extraction is one of the most important techniques for separation and purification of rare-earths [1]. In practical industrial-scale process, however, group-separation of rare-earth ions by traditional aqueous-organic biphasic system have to be conducted by repeated liquid-liquid twp phase equilibrating at carefully selected solution pH values. Repeated adjustments of solution pH value are always required to achieve separation of light, middle and heavy rare-earth ions [2,3]. This work aims to solve purification of rare earth from such impurities as Al, Fe and Si, as well as one-step separation of multiple rare-earth ions by a proposed novel strategy of three-liquid-phase extraction (TLPE). The three-liquid-phase system used for TLPE is composed of organic top phase, polymer-rich middle phase and salt-rich bottom phase. Experimental results indicate that co-existed non rare-earth impurities, such as Al(Ⅲ), Fe(Ⅲ), Si(Ⅳ), can be selectively enriched into the top organic phase and polymer-rich middle phase of TLPS, respectively, while most rare-earth ions remain in salt-rich bottom phase. And then, group separation of light, middle and heavy rare-earth ions, such as La(Ⅲ), Eu(Ⅲ) and Yb(Ⅲ), respectively into bottom aqueous phase, polymer middle phase and top organic phase can be achieved after removing impurities. The present works indicate that three-liquid-phase extraction is a promising separation method to treat the complex solution containing multiple rare earths and non rare-earth impurities.

Salt-lake brines are important mineral resources of lithium (Li), boron (B) and magnesium (Mg) [1]. However, recovery of Li and B from high concentrated Mg brines after removing sodium and potassium are difficult due to high Mg/Li concentration ratios [2]. In comparison with traditional sedimentation and adsorption methods, solvent extraction of Li and B from slat-lake brines exhibits obvious advantages in high recoveries, separation selectivity, and economical efficiency [3]. In present work, a novel three-liquid-phase extraction technique is proposed for separation of lithium and boron from high concentrated magnesium brine of salt lake. The experimental results indicated that in three-liquid-phase system of TBP-PEG-(NH4)2 SO4-H2O, Li and B could be extracted and separated into the top organic and middle polymer phases respectively, while most of Mg and other impurity were left and enriched in the bottom aqueous phase. The separation factor of Li/B between organic top phase and polymer middle phase was considerably high. Various influences on extraction and separation of Li and B in the three-liquid-phase system were investigated, including initial H+ and Cl-concentrations, molar ratio of Fe to Li, added amount of PEG and (NH4)2SO4 , TBP content in organic phase. The present work highlights a promising technique to extract and separate Li and B from salt-lake brine with high Mg/Li ratio. By this technique, the recovery and separation of Li and B can be achieved simultaneously within one step of extraction. The new method opens up an entirely new approach to realize comprehensive exploitation of salt lakes in China.

PEO-PPO copolymer has shown increasing application to separation due to its versatile phase behavior, thus a corrective understanding on the process of its phase behavior can provide sounder basis for realistic applications. Many literatures have reported that salt ions can exert a great influence on the phase behavior of PEO-PPO copolymers in the solution. Whereas the mechanism has not been reached and the dispute is mainly focused on whether the salt ions have a direct interaction with PEO- PPO copolymers. In this study, FTIR and Raman spectroscopy have been employed to provide molecule-level evidences that there is direct interaction between PEO-PPO and the salt ions in aqueous solutions. For EOPO-K2CO3 and EOPO-Na2CO3 systems, the IRv(C-O) of PEO segment first exhibits a red shift and then undergoes a blue shift, while the Raman v as (-CH2 -) band first exhibits a blue shift and then undergoes a red shift with increasing salt concentration. Based upon the spectral results and relevant literatures, we are convinced that there are direct interactions of potassium ions with the ether oxygen atoms in PEO-PPO molecular chain. In addition, the experimental results on EOPO-KSCN and EOPO-NaSCN systems reveal that the poorly hydrated anoin, thiocyanate, also has a direct interaction with EOPO molecules. This study helps us gain insight into the mechanism of ions modulating the phase behavior of EOPO molecules.

PEO-PPO block copolymer has been found various applications in these fields such as bimolecular separation, soil remediation and drug delivery due to its versatile phase behavior in aqueous solutions. Many literatures have reported that salt ions can exert a great influence on the self-assembly behavior of PEO-PPO copolymer molecules [1]. Whereas the mechanism has not been reached and the dispute is mainly focused on whether the salt ions have a direct interaction with PEO-PPO copolymers [2, 3]. In this study, FTIR and Raman spectroscopy have been employed to provide molecule-level evidences that there is direct interaction between PEO-PPO and the salt ions in aqueous solutions. For EOPO-K2CO3 and EOPO-Na2CO3 systems, the IR v（C-O） of PEO segment first exhibits a red shift and then undergoes a blue shift, while the Raman vas （-CH2-） band first exhibits a blue shift and then undergoes a red shift with increasing salt concentration. Based upon the spectral results and relevant literatures [4], we are convinced that there are direct interactions of potassium ions with the ether oxygen atoms in PEO-PPO molecular chain. In addition, the experimental results on EOPO-KSCN and EOPO-NaSCN systems reveal that the poorly hydrated anoin, thiocyanate, also has a direct interaction with EOPO molecules. This study helps us gain insight into the mechanism of ions modulating the phase behavior of EOPO molecules.

Capture and storage of carbon dioxide(CO2)from flue gas is drawing increasing interest as a potential method for the control of greenhouse gas *** liquid-based hybrid solvents are expected to retain the desired properties of ionic liquids(ILs)for CO2 capture but avoid many inherent drawbacks,such as high viscosity in their unreacted states.
