| 520 | 3 | |a Highly concentrated (up to 3.56mol L-1) binary solutions of NpO2NO3 were prepared to investigate the self-association of Np(V). By using visible/NIR absorption spectrophotometry and chemometric techniques, Np(V) was shown to be only monomeric below 0.2mol L-1, to exist under its monomeric and dimeric forms between 0.2 and 2mol L-1, to begin to form self-associates of higher degrees above 2mol L-1. In the range 0.2mol L-1 < CNp(V)<2mol L-1, the neptunium distribution between the free NpO2+ and dimeric (NpO2)22+ forms was determined by Raman spectroscopy. The simple solution concept was used to establish the activity function for the reaction of dimerization. Such a water activity function can be used to calculate the apparent dimer formation constant for any solution of known composition and water activity, provided that this solution is simple. | |
