Description
The process for actinides (III) partitioning using solvent based on N,N,Nꞌ,Nꞌ-tetraocthyl-diglycolamide (TODGA) in meta-nitrobenzotrifluoride (F-3) was proposed. The process involves actinides(III) and REE co-extraction, Zr and Pd removal, HNO3 scrubbing, selective recovery of actinides with DTPA buffer solution and subsequent stripping of REE. The dynamic test using mixer-settlers was carried out. The feed solution contained about 4.5 g/L REE and trace amounts of 241Am. As found, the degree of americium recovery was no less than 99.97%. The decontamination factor of REE removal from Am product was about 100. Most of the zirconium, molybdenum and palladium were found in the raffinate. (author)
