Physicochemical Characterization and Antimicrobial Properties of Lanthanide Nitrates in Dilute Aqueous Solutions.

ABSTRACT: This work presents the results of studying dilute aqueous solutions of commercial Ln(NO₃)₃ · xH₂O salts with Ln = Ce-Lu using X-ray diffraction (XRD), IR spectroscopy, X-ray absorption spectroscopy (XAS: EXAFS/XANES), and pH measurements. As a reference point, XRD and XAS measurements for characterized Ln(NO₃)₃ · xH₂O microcrystalline powder samples were performed. The local structure of Ln-nitrate complexes in 20 mM Ln(NO₃)₃ · xH₂O aqueous solution was studied under total external reflection conditions and EXAFS geometry was applied to obtain high-quality EXAFS data for solutions with low concentrations of Ln³⁺ ions.
