This work extends the radioisotope studies to include, 241-Am, 236-Pu for their importance in the treatment of spent nuclear fuel (241-Am also has a wide use in smoke detectors) and 51-Cr, 59-Fe, 54-Mn, 65-Zn which are present in nuclear wastes from neutron activation in nuclear installations, as well as those arising from medical uses.
Measurement of distribution coefficients enabled the construction of selectivity series which demonstrated the versatility of the phases for scavenging specific isotopes.
