Use of electrospray ionization mass spectrometry for the characterization of actinide complexes in solution

چکیده
In order to understand the mechanisms involved in the extraction processes developed to separate minor actinides, the “ligand/metallic cation” complexes formed in the organic phases are characterized by electrospray ionization-mass-spectrometry (ESI-MS). This paper deals with the application of the ESI-MS technique to analyze americium complexes in organic solutions. Two extractant systems are investigated : 1/ organic solutions of nitrogen polydentate extractants such as 6,6’-bis(5,6-dialkyl-1,2,4-triazin-3-yl)-2,2’-bipyridines (BTBPs) and 2/ organic solutions composed of mixture of a malonamide and a dialkylphosphoric acid.
