Comment: |
average non-electrostatic SC constant of 11 sets of batch sorption experiments on hematite from [C96]; standard deviation relate to the differences in fitted logK constants from the various batch sorption data sets; IS ranges from 0.001 to 1 M; under relatively constant carbonate alkalinity (~5E-5 mol/L HCO3<1->); reaction equation obviously wrong |
