Description
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 β1 = 1.32 (I 1 M), 1.49 (I = 3 M), or 1.47 (I = 5 M), while that of Pd(NO3)2 to be β2 = 0.45 (I = 3 M) or 0.14 (I = 5 M). (author)
