“…On the other hand, PC was utilized as a diluent in some extraction studies [20,21]. According to our analytical scheme, when PC was used as a diluent it avoided addition of solvent in the tested extract because it allows the organic extraction phase to be directly investigated by the electroanalytical method.…”

“…Generally, since the extracting solvent affects to extractability in the ion association extraction systems more strongly than that in chelate extraction system, PC was mainly examined in the former systems. For example, B. G. Stephens Vol.29 No.3 (2018) et al has reported the extraction of ferroin complexes using PC as a solvent with different derivatives of 1,10-phenanthroline [3][4][5] , and PC was also used for the extracting solvent in the polarographic determination of halo-complex ions of some metals 6,7) . On the other hand, only few attempts to applying PC to chelate extraction system were reported 8,9) , and the paper on the solvent extraction of metal ions using BC could not be found at all by reviewing the literature.…”

4-Methyl-1,3-dioxolan-2-one and 4-ethyl-1,3-dioxolan-2-one are well-known solvent in the name of propylene carbonate (PC) and butylene carbonate (BC), respectively, and PC is classified to level 1 in terms of combustibility and health hazard by National Fire-Protection Association. Therefore, PC is less toxic and environment-friendly solvent compared to the usual solvents, such as hexane and toluene. PC and BC are not only safe but also are having strong polarity, however, their application to solvent extraction of metal chelates as an extraction solvent were not carried out so much. Then, in this study, PC and BC were applied to N,N-dioctyldiglycolamic acid (DODGAA) extraction of lanthanides as the diluent and their extractabilities were compared with that of hexane. Lanthanum and scandium were found to be affected with solvent comparatively strongly to the other lanthanides. It was observed in the slope analysis of in the relationship between log D vs. pH plots that the some slopes of straight lines in DODGAA-PC and DODGAA-BC system deviated from theoretical value of 3. The possibilities of the change of metal ion concentration based on the volume change due to the mutual dissolution and the formation of different kind of complex other than LnR 3 were considered as the causes for the deviations in a slope analysis and were examined experimentally.

Abstract4-Methyl-1,3-dioxolan-2-one is well known solvent in the name of propylene carbonate (PC) and has good solvent properties, e.g. low toxicity, less flammable, high density and less viscous, nevertheless the application of PC in solvent extraction has only been considered in a few cases. Then, availability of PC to solvent extraction was examined by applying it to the extraction of three different kinds of analyte, hydrophilic neutral species, a chelate and an ion association complex. At first, 6 water miscible solvents, i.e., methanol, isopropanol, tert-butanol, acetone, acetonitrile and tetrahydrofuran were arbitrarily selected as hydrophilic neutral species and the extractability of PC and cyclohexane for these solvents were examined. Dioctyldiglycolamic acid (Abbreviate as DODGAA) complex of lanthanide (Ln 3+ ) was chosen as an example of chelate extraction and was extracted with PC and n-hexane, respectively. Ion association extraction was investigated with the extractability of bis(1,10-phenanthroline) iron(II) complex (Fe(phen) 3 2+ 2X -) by using PC, toluene and nitrobenzene. In all cases, PC showed the significant extractability compared to common solvents.
