Extraction Properties

A N,N-dibenzylacetoamide derivative of p-tert-octylcalix[4]arene was synthesised and its solvent extraction of precious metals in nitric acid media was investigated for determining the effects of extractant concentration and contact time as well as nitric acid concentration in comparison with a N,N-diethylacetoamide derivative. The extraction properties with both derivatives exhibited a slight difference. The extraction reaction of divalent palladium with both derivatives is discussed by slope analysis. The stripping behaviour of the extractant loaded with silver and palladium is also described using various stripping solutions.

AbstractExtraction behavior of tris(2-methylbutyl) phosphate (T2MBP), a higher homologue of tri-n-butyl phosphate (TBP), in the extraction of U(VI) and Pu(IV) from nitric acid media has been evaluated in the present study. Distribution ratios for the extraction of these metal ions by T2MBP were measured as a function of equilibrium aqueous phase nitric acid concentration, extractant concentration and temperature to understand the temperature effects on extraction. Enthalpies of extraction of T2MBP/n-dodecane-U(VI)-HNO3and T2MBP/n-dodecane-Pu(IV)-HNO3systems were calculated from the distribution ratio data using “second law” method. The data reveal that the extraction of U(VI) by T2MBP is exothermic in nature, whereas that of Pu(IV) is endothermic.
