Extraction Of Metals

This work presents the experimental study results of Fe(III) and Zn(II) extraction by ionic liquids based on trioctylmethylammonium chloride and rhodanide in an aqueous two-phase system based on polypropylene glycol 425 and sodium chloride. Based on the results obtained, it was concluded that these extractants are effective for the extraction of metals from aqueous solutions, and aqueous two-phase systems represent a “green” alternative to traditional extraction systems.

This paper attempts to study and optimize the affinity partitioning conditions of papain in an aqueous two-phase system (ATPS). The effect of the amount of ionic liquids (ILs), the concentration of K2HPO4, temperature, pH, and the volume of papain solution were discussed concretely. The optimum conditions were determined as ionic liquid was 1.4 g and K2HPO4was 1.4 g, the extraction efficiency of papain could reach 98.33% with pH unadjusted. The temperature and the pH of the solution are major parameters that influence the partitioning of protein in ILs-based ATPSs. The partition of papain to the IL-rich phase was enhanced by increasing the amount of ILs, the concentration of K2HPO4, and temperature, especially at its isoelectric point.
