Structure and Aqueous Solubility of Sodium Isosaccharinate
It has been recently shown that isosaccharinic acid, C6H12O6 (ISA), and its derivative salts have a great potential for practical application in the area of nuclear waste treatment and disposal sites management. Several studies demonstrated the effect of ISA complexation on radionuclide solubility and sorptive properties, especially on actinides in (+4) oxidation state like Np(IV) and Th(IV). The presence of ISA and/or its derivatives strongly affects the migration of radionuclides by increasing their solubility in water by several orders of magnitude and Na-ISA has been proposed as a component of decontamination formulations for actinide-contaminated surfaces. Here we report the synthesis, crystal's structure and characterization (FTIR, TGA) of sodium isosaccharate, NaC6H11O6-H2O (Na-ISA). The structure has been solved by single crystal X-ray diffraction methods. The solubility of Na-ISA has been evaluated and compared to that of Ca-ISA based on the structural features of both compounds.
