A solvent extraction method using a mixture of 0.1M thenoyltrifluoroacetone and 0.1M tributylphosphate in carbon tetrachloride has been developed for the separation and purification of 228Ac in 228Ra solutions. The 228Ra was first purified by a preliminary extraction cycle. The 228Ac which had accumulated int his 228Ra fraction after the purification was separated and purified by a second solvent extraction cycle. Since commercially available 228Ra solution very often contains 226Ra, the γ-radioactive decay products of the 228Ra have to be carefully removed. The 228Ac thus prepared was found to be pure enough for use as tracer.
