✦ Synopsis

An ion exchange method for the separation of pure 22Na from bombarded Mg targets has been developed. Mg is complexed by citrate at a pH of 8 in a 40% methanol solution and is eluted, while 22Na is retained on the resin. Triethanolamine is used for pH adjustment. 22Na is eluted with ammonium carbonate. Distribution coefficients for the ionic species of interest have been determined. The apparatus used in a hot cell for this radiochemical separation is described.
