Hydrodynamic Properties of Tris(2-methylbutyl) Phosphate and Tri-<i>n</i>-alkyl Phosphates in <i>n</i>-Dodecane – A Comparative Investigation between Unirradiated and Gamma Irradiated Solvent Systems

The physicochemical parameters of tris(2-methylbutyl) phosphate (T2MBP), a molecule possessing the essential characteristics required to be considered as promising extractant in solvent extraction stage fast reactor fuel reprocessing, have been evaluated present study. In this context, density, viscosity and interfacial tension (IFT), which are few among important selection criteria prior its deployment plant scale measured for T2MBP n-dodecane (n-DD) based systems. Similar studies performed with straight chain isomer, tri-n-amyl (TAP) well widely utilized commercial extractant, tri-n-butyl (TBP) so emphasize on structural effects. Though trends behaviour TBP systems (temperature ligand concentration effects) known literature, data generated work comparison results under similar experimental conditions. Solutions trialkyl phosphates (TalP) n-DD different concentrations used generate variation IFT change concentration. addition, transformation their properties has assessed after subjecting solvents various levels gamma absorbed doses. Overall, it observed that there was no significant density irradiated TalPs; however, rise reduction TalP samples upon irradiation. Gibbs energy activation 1.1 M TalP/n-DD solutions by fitting respective dynamic value function temperature using Andrade’s equation. Moreover, from value, relating activity determined Szyszkowski adsorption isotherm.
