The interaction of NpO2+ with Cl- was studied using visible-near-infrared spectroscopy in NaCl-CaCl2-NaClO4, NaCl-NaClO4, and CaCl2-NaClO4 solutions with ionic strength (I) of 6M. The spectra of NpO2+ around 980 nm varied with Cl- concentration in the NaCl-CaCl2-NaClO4 and NaCl-NaClO4 solutions at [Cl-] >= 3.5M, but not in the CaCl2-NaClO4 solution. Assuming the 1: 1 interaction between NpO2+ and Cl-, the apparent equilibrium constants at I = 6M were evaluated. The presence of Ca2+ was found to destabilize overall interaction between NpO2+ and Cl-. The observations were consistent with the density functional theory calculation.
