Abstract
The extraction behavior of DB21C7-HPW synergistic system for Cs has be en investigated and compared with that of DB21C7. Two simulated radioa ctive waste have been examined. It shows that this synergistic system is not only effective for ordinary waste SAW1, but also for the waste of high concentration of nitrates (SAW3). An extraction percentage 99. 1% of Cs of SAW3 was obtained by an extracting stage of 5 and scrubbin g stage of 3. The stability of synergistic agents towards radiolysis i s satisfied and the selectivity for Cs is quite good. Both the additiv e compound and the extracted Cs complex of DB21C7 and HPW have been se parated and identified.
