Synergistic extraction of uranium(VI) from nitric acid solutions by foams loaded with solutions of HDEHP and TBP in o-dichlorobenzene [K. Shakir, Sh. Beheir, M. Aziz] The effect of added TBP on the extraction of uranium(VI) with a solution of di-(2-ethylhexyl)-phosphoric acid (HDEHP) in o-dichlorobenzene from nitric acid solutions has been investigated at varying concentrations of nitric acid, HDEHP, TBP and uranium(VI). The mechanism of the synergistic effect of TBP is discussed on the basis of the results and can be summarized in the following equation: UO 2(aq) 2+ +0.67(HX)3(o)+2TBP(o)⇆UO2X2·2TBP(o)+2H (aq) + where HX denotes HDEHP and the HDEHP loaded on the foam is trimerized.
