“…Over a number of years, different methods have been used for metal ion extraction. These methods have been ion exchange [5], adsorption [6], chemical precipitation [7], membrane separation [8], and solvent extraction [9,10,11]. However, most of the above methods come with certain disadvantages, such as high consumption of organic solvents, incomplete extraction of metal ions, and the high cost of the chemicals.…”

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.

“…Likewise, the extractability of REEs with weak acidic resins containing carboxylic functional groups viz. D113-III and D152 resins was reported by Xiong et al (2008Xiong et al ( , 2009 [80,81]. Moreover, chelating resins containing iminodiacetic or phosphonic functional groups instead of sulfonic acid was also studied for REEs [82].…”

This work aimed to study the potential for bioremediation of lanthanum by microalgae Ankistrodesmus sp. and Golenkinia sp., as free cells and immobilized in calcium alginate pellets. To reach that goal, studies have been conducted in batch and in continuous fixed bed column. Kinetic models of pseudo-first order and-second order and equilibrium isotherms of Langmuir and Freundlich were used to predict the metal accumulation behavior by free and immobilized biomass in a batch system. The data were best fit to kinetic model of second order, with coefficients of determination (R 2) greater than 0.98. Free cells were more efficient in the process than alginate pellets and it was not possible to model the results due to the very fast uptake. Equilibrium modelling indicated that both free and immobilized cells, as well as alginate pellets results were best fit to Langmuir equation due to the high R 2 value and similarity with experimental results. Dynamic column tests conducted with Ankistrodesmus sp. and Golenkinia sp. immobilized cells during 8 hours presented 80% efficiency in the removal of the metal, without reaching saturation. The high and fast ability of the microalgae to adsorb lanthanum corroborates their potential large-scale application.
