Modeling of simultaneous extraction of uranyl nitrate and nitric acid by 36 vol.% tri-iso-amyl phosphate in n-dodecane

Abstract The simultaneous extraction of uranyl nitrate and nitric acid by 36 vol.% tri-iso-amyl phosphate (TiAP) in n-dodecane was experimentally studied and modeled. The batch extraction experiments were carried out at low concentration region of aqueous uranyl nitrate by 36 vol.% TiAP in n-dodecane at 25 °C. The non idealities in aqueous phase were described by eNRTL model. The predicted organic phase concentration of nitric acid and uranyl nitrate obtained by considering the $ HNO_{3} $·TiAP and $ UO_{2} $($ NO_{3} $)2·2TiAP species in the organic phase is in good agreement with the experimental data..
