Chemistry of actinides and lanthanides. New extractants and separation methods

Basic chemistry can still open new ways for actinides separations for analytical and industrial purposes. In this paper are discussed: reprocessing of spent nuclear fuels, for which dialkylamides seem to be an advantageous alternative to TBP; extraction of actinides from the high radioactive wastes acidic nitrate solutions by N,N'dimethyldialkylmalonamides which are extractants forming lower amounts of wastes than the carbamoylmethylenephosphonates; use of nitrogen or sulfur donors extractants for trivalent actinides lanthanides group separations which permits group separations from low pH nitric acid solutions
