Abstract

Palladium complexation in concentrated nitric acid solutions was studied by UV/Vis absorption spectrophotometry. The ionic strength of the solutions was fixed to I = 1, 3, or 5 mol dm^-3 (M) by mixing of HNO₃ and HClO₄. The major palladium species were found to be Pd²⁺, PdNO₃ ⁺, and Pd(NO₃)₂. The formation constant of PdNO₃ ⁺ was determined to be β ₁ = 1.32 (I = 1 M), 1.49 (I = 3 M), or 1.47 (I = 5 M), while that of Pd(NO₃)₂ to be β ₂ = 0.45 (I = 3 M) or 0.14 (I = 5 M).
