Separation of trivalent actinides and lanthanides using dithiophosphinic acids - End of Studies Project
Abstract : This report presents the results of the degradation study of the active compound of the commercial extractant CYANEX ® 301, bis(2,4,4-trimethylpentyl)dithiophosphinic acid. It was determined that the complete degradation, which is commonly thought to produce the oxo equivalent, is in fact a two-step process where the first product to be obtained is relatively stable and corresponds to a condensation more than a degradation. A study on the impact of some parameters of the condensation, such as the concentration of oxidizer or acid and the atmosphere, has enabled us to propose here a general equation of the degradation of CYANEX ® 301.
