apparent stability constant for I=0, for conversion to other ionic strengths, activity constants of all surface species are assumed equal to one; no electrical double layer correction to the mass laws for charged surface species; fit with U(VI) adsorption data [KD01] over the entire pH range and the thermodynamic set in table 2-1 of [DKP01]; termed model B4; fit for pH<6: log K=-5,23 and thermodynamic set of (KCKD96) (without formation of ternary surface complex, termed model B2) cited in [K02b] |
