>A method is described for the separation of Pm/sup 147/ from a samarium proton-synchrocyclotron target without the use of a carrier. The initial separation was carried out by electrolysis at a mercury cathode. Optimum conditions were a concentration of 50 mg Sm/sub 2/O/sub 3/ per ml electrolyte, containing 190 mgl/ml potassium citrate. pH 5 to 6. cathodic current density 50 ma./cm./ 2/, temperature 0 to 5 , and renewal of mercury at 1-hr intervals. After 4 hr the solution contained 99.5% promethium and only 8% samarium. The final separation was carried out by ion exchange in a column packed with Dowex-50 or KPS-200 resin in the NH/sub 4/ form. Elution was carried out with trihydroxyglutamic acid or with lactic acid.
