Abstract

Optical absorption features for ⁷F_0′→⁵L_6′ and ⁷F_0′→⁷L_6′ transitions of trivalent americium ion were investigated in a wide range of aqueous combinations of perchloric and nitric acids (0.1–6.0 mol L⁻¹). The developed qualitative matrix of extinction coefficients measures the cumulative impact of increasing electrolyte content, changes in the hydration zones of americium ion, and inner-sphere perturbation by nitrate on the absorbance. The effects of growing complexity of aqueous electrolyte medium were highlighted for the ⁷F_0′→⁵L_6′ transition. Spectroscopy indicates the perturbation of the inner hydration sphere of trivalent f-element by one nitrate ligand.
