摘要：

These studies are an extension of earlier work on the recovery of actinides extracted by Truex solvent from simulated high level waste solution, with a mixture of weak acid, weak base and complexing agent used as a strippant. The effectiveness of the proposed strippant, consisting of formic acid, hydrazine hydrate and citric acid, is tested in a counter-current mode using mixer-settler in the present studies. The studies show that near quantitative recovery of americium and plutonium is feasible from acid-bearing Truer solvent with no reflux (reextraction) of activity. Use of this strippant reduces considerably the generation of secondary waste.
