McCabe, R. Ditchburn, N. Whitehead] We give a new general method of separation of the title radionuclides, using ferric hydroxide precipitations, cation exchange chromatography followed by anion exchange for U, further cation exchange for Pa and direct elution for Th. Electrodeposition for all three elements is from sulfate medium. Yields for Pa, Th, Pa, U are mostly about 98%. Matrices analyzed include calcite, dolomite, phosphorite, sediments, organic material, and mineral fractions from rock. Akadùmiai Kiadó, 1992 McCabe W.
