In order to accurately measure the decay data of short-life nuclide 142La, it is necessary to isolate and prepare radiochemical pure 142La solution from fission products. For the aim, the plan is made for isolating Ba from fission products first, and then isolating La that grows from Ba. So the separation of La-Ba becomes the key for solving above problem.A convenient method that realizes the separation of high-valent ionic La3+and low-valent ionic
