摘要：
Displacement-extraction of tracer concentrations of Po-210 in 1.0M (H, Na)NO3 solutions has been studied by using copper dithizonate-CCl4 solutions. Furthermore, based on the results of the displacement-extraction of polonium, a mixture of Po-210, Bi-210, and Pb-210 of tracer concentrations in 1.0M (H, Na)NO3 solutions could be satisfactorily separated with successive extractions by copper dithizonate-CCl4 and dithizone-CCl4 solutions in acidic conditions.
