Comment: |
cation surface complexation constants for formation of the species »FeO-M<1+> are plotted against the first hydrolysis constants, these linear free energy relationship (LFER) correlations were used to predict SC constants for similar cations for which limited or no sorption data exist; details also in [M95b] |
