Comment: |
Na-Illite; sorption edge measurements; 2SPNE SC/CE model; original reaction equation in the study: »X(s)-OH + PaO(OH)<2+> + H2O = »X(s)-O-PaO2(OH)<1-> + 3 H<1+> with logK = -6.7; formation constant logK = -1.24 for the equation PaO(OH)<2+> = PaO2<1+> + H<1+> (Trubert et al. 2003); same protolysis data as in [BB09a] |
