AbstractAbstract
[en] In the framework of DIAMEX-SANEX process for minor actinide partitioning, the degradation by hydrolysis and/or radiolysis of extractant molecules which are the extractant of minor actinides from high level liquid radioactive waste are studied. Qualitative studies were performed using mass spectrometry (gas chromatography - mass spectrometry: GC-MS and liquid micro-chromatography in reversed phase - electro-spray - mass spectrometry: RPLC-ESI-MS) and NMR. The chromatographic methods were optimized to analyze organic phase. The main compounds were identified and their concentrations were measured. (authors)
