| Abstract: | A novel composite bead incorporating tri-isoamyl phosphate (TiAP) within polyethersulfone (PES) matrix was developed. Subsequently, advanced analytical tools like scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA) were employed for ascertaining the inclusion of the extractant (TiAP) within the PES bead. Later these beads were evaluated for their ability to extract hexavalent uranium (U(VI)) and trivalent americium (Am(III)) from aqueous acidic feed. In this study various parameters, impacting the distribution coefficient (Kd) like different acid medium, acid concentration, actinide metal ion concentration, and ligand concentration were investigated. The nitric acid medium was found to be the best medium for the extraction studies. The results indicated initial increase in the Kd value upto 3 M followed by decrease in nitric acid medium for both the actinides. The sorption equilibrium was attained rapidly within 15 minutes and the kinetic data followed pseudo second order kinetics for both the actinide ions. The maximum loading capacity for U(VI) was determined to be 154.08 mg/g following the monolayer chemi-sorption mechanism as per Langmuir isotherm model. Thermal analysis revealed endothermic behavior of the sorption process. The loaded U(VI) from the beads was efficiently stripped using 0.5 M sodium carbonate solution. Notably, the beads maintained their performance well throughout 5 cycles of sorption and desorption steps, demonstrating their reusability capacity. The experimental outcomes illustrate that the TiAP-PES composite beads have great potential for the U(VI) separation selectively over Am(III) from the acidic waste stream. [ABSTRACT FROM AUTHOR] |
