ملخص: The liquid-liquid extraction of uranyl nitrate by tetrabutylalkylenediphosphonates (TBADP) and TBADP-di(2-ethylhexyl)phosphoric acid (D2EHPA) mixtures from aqueous solutions of nitric acid was investigated. The tetrabutylalkylenediphosphonates tested for extraction were: tetrabutylmethylenediphosphonate (TBMDP) and tetrabutylethylene-diphosphonate (TBEDP). The results of the extraction tests have revealed a synergistic effect when mixtures of TBADP-D2EHPA are used.
