Comment: |
average non-electrostatic SC constant of 17 curves from [DA96], [HL85], [VT98] and [WDPWX94] for the sorption on Ferrihydrite, Goethite and Hematite; standard deviation relate to the differences in fitted logK constants from the various batch sorption data sets; IS was 0.01, 0.02, 0.1and 0.5 M |
