Investigations of the pH-Dependent Adsorption of Uranyl Species on Phosphorylated Cellulose-Nanocrystal Ferrihydrite: Insights from Combined Raman Spectroscopy and Computational Analyses
exhibits significantly slower adsorption kinetics than the other complexes at all pH values. These results were also supported by IR spectroscopy and DFT modeling, revealing fundamental differences in interaction pathways that govern uranyl binding. Raman adsorption data were found to fit a pseudo-second-order model. The findings provide mechanistic insight essential for the rational design of species-specific and pH-optimized uranium remediation strategies for water utilities.
