Cation exchange behavior of actinium‐228 in mixed solvent system consisting of methanol‐thiocyanate‐water was studied with Dowex 50 resin. Solvent systems containing 50 to 90% methanol and concentration of thiocyanate from 1F to 5F were used. The distribution ratios of actinium between resin and the solutions were estimated by batch equilibrium and elution peak methods. By plotting these distribution ratios for each solvent system against the concentration of thiocyanate, different correlations were found. The difference may be attributed to the fact that the different species were absorbed by the resin. Feasibitity of using the mixed solvent system to the separation of actinium from thorium, was also examined.
