| Comment: |
total number of surface sites was approximated assuming a 1:1:2 stoichiometry between calcium, magnesium, and carbonate sites exposed at the dolomite surface; SSD value was assumed; pCO2 1E-3.5, 0.01, and 0.96atm; PZC=6.9+-0.2 at sumCO2=0.014 M and [Ca2+]=0.0025M; PZC=8.0+-0.2 at sumCO2=0.001 M and [Ca2+]=7E-4 M and [Mg2+]=0.002 M; C?; 25+-0.2°C; surface concentration 150-200m^2/L |
