OSTI ID:4258682

Recovery of Pa from irradiated Th is described. The Th is dissolved in HNO/sub 3/ and, if necessary, the Pa is carried down in repeated MnO/sub 2/ precipitations. The Pa solution thus obtained or the crude HNO/sub 3/ solution is passed over phenol-formaldehyde resin on which the Pa is adsorbed. The Pa is eluted from the resin with NH/sub 4/F or HF aqueous solution. (T.R.H.)
