Comment: |
Slightly varied surface complexation constants (Table 3 - values in brackets, log K = -4.6 in [BB09a]) are taken for scoping calculations in order to provide for a better fit to the experimental data (see discussion in the text); cation exchange reaction: 3 Na-clay + Eu<3+> = Eu-clay + 3Na<1+>, log K = 1.9
