Description
The present work is aimed at studying the extraction systems based on neutral organophosphorus extractants - phosphorylated calixarenes for recovery of Pd and Tc together with Am and Cm from high-level radioactive wastes. Extraction of Pd, Tc and Eu (Am) was studied for phosphorylated calixarenes in meta-nitrobenzotrifluoride (NBTF). Main results are presented in Table. On the basis of available data one can suggest that type and position of phosphor-organic substituents are not so important for extraction of Tc and Pd, as for Eu and Am extraction. The phosphorylated at upper rim calix[4]arenas with small alkyl substituents at phosphorus atom are of prime interest for joint recovery of europium, americium, technetium and palladium. (authors)
