BACK EXTRACTION METHOD OF Am (III) AND Pu (IV) IN ORGANIC SOLVENT INTO NITRIC ACID BY N, N, N', N'-TETRAMETHYLDIGLYCOLAMIDE (TMDGA) COMPOUND

摘要

PPROBLEM TO BE SOLVED: To provide an efficient back extraction method of Am, Pu after extracting trivalent, tetravalent actinoid ions from spent fuel or high level radioactive waste liquid, which is an important matter in process development in the nuclear field. PSOLUTION: TMDGA(N, N, N', N'-tetramethyl-1,3-oxapentanediamide), one of DGA compounds, is provided as a complexing agent. PCOPYRIGHT: (C)2006,JPO&NCIPI
