An extraction procedure has been developed for the successive isolation of carrier-free sodium 22 and aluminum 26 from deuteron- (proton-) irradiated magnesium targets. The irradiated magnesium metal or alloy target is dissolved in sulfuric acid and the pH adjusted to 1.0-1.5 with ammonia. Sodium 22 is extracted with a chloroform solution of 15-crown-5 and picric acid and back-extracted with water in the presence of tetraphenylphosphonium chloride or a tetraalkylammonium chloride. Then aluminum 26 is extracted by trioctyl-ammonium oxalate in benzene (toluene) containing chloroform and back-extracted with 6M hydrochloric acid. The yields of sodium 22 and aluminum 26 are better than 95%.
