Carrier facilitated transport of uranium across supported liquid membrane using dinonyl phenyl phosphoric acid and its mixture with neutral donors

► Permeation of U(VI) from nitric acid medium across supported liquid membrane. ► DNPPA without/with Cyanex 923, TOPO, TBP, and TEHP in n-paraffin as carriers. ► U(VI) permeation increased in the order: Cyanex 923 ~ TOPO > TBP > TEHP. ► U(VI) permeation across SLM maximum at 1:2.5 mole ratio of DNPPA and Cyanex 923. ► Relevant for uranium removal from nitric acid waste solutions emanating from process plants/analytical labs.
