Abstract: The stripping behavior of actinide elements loaded in 30% TRPO-kerosene solution with nitric acid,oxalic acid and sodium carbonate solution is studied and stripping parameters are given. Americium and lanthanide elements can be effectively stripped with 5-6mol/l nitric acid,but at higher nitric acid concentration third phase would appear. More than 99% neptunium and plutonium could be recovered in two times stripping by 0. 5 mol/l oxalic acid with crossflow. Uranium is stripped with sodium carbonate. The cross contamination between the three fractions are very little. A proposed flowsheet for the removal of actinide elements from high level radioactive waste by TRPO extraction is presented.
