Abstract
The impact of α-D-isosaccharinic acid (HISA, main degradation product of cellulose) on the solubility, complexation and redox behavior of plutonium is evaluated using a combination of solubility experiments, advanced spectroscopic techniques and DFT calculations. Three new Pu-ISA complexes are identified, and the most comprehensive thermodynamic dataset available to date for the system Pu(III)-Pu(IV)-ISA is derived. This model is valid under a wide range of boundary conditions relevant in the context of nuclear waste disposal.298
