The fit values obtained by modeling are compiled in Table . The obtained fit values are consistent within a set of chemically similar systems, i.e., they are comparable for each added salt. For example, for NaNO 3 , we find growing values of H p for increasing amounts of salt added while the slopes of both fitted domains stay approximately constant. In the case of NaCl, the trend is similar; however, at the highest concentration of 2000 µmol g -1 , the last domain is not reached anymore within the duration of the experiment. Therefore, the value of H p is less relevant here because the experimental data could also
