SYNERGETIC AND EFFICIANT EXTRACTION STUDY OF SOME LANTHANIDE (III) IONS BY USING 8-HYDROXYQUINOLINE WITH GREEN PHASE TRANSFER CROWN ETHER EXTRACTANTS IN ORGANIC MEDIA FROM STRONG ACIDIC MEDIA
Abstract: The aim of present investigation was the study of extraction ability of 8-hydroxyquinoline in presence of DCH18C6, DB18C6, and DBP18C6 crown ethers for selected lanthanide (III) ions from acidic media to DMSO/CHCl3 solvent system. The influence of nitric acid concentrations on selectivity of extraction were studied in relation to pH, D and ? values. The effects of pH of medium, Solvent, Crown ether ligands and concentrations of crown ethers were also studied on synergetic extraction of lanthanide(III) ions. Very interesting results were observed for synergetic and efficient extraction of Ln(III) ions from acidic media to DMSO/CHCl3. The crown ether DCH18C6(Dibenzo Cyclohexyl 18-Crown-6) had shown high separation ability for Ln(III) ions for optimum 5 µM concentration at acidic pH equal to 3.8 from strong acidic media with 8-hydroxyquinoline as compared to original 18C6 and other derivatives. This simple, efficient and rapid liquid-liquid synergetic extraction method of Ln(III) ions and rare earths found perspective applications as an analytical method for their separation and extractive spectrometric determination.
