| Comment: |
SSD calculated from SSA and difference between maximal sulphate adsorption capacity and that of goethite (4.2 sites/nm^2); PPZC determined by potentiometric titration; temperature 25+-0.1°C in N2 atmosphere; pK assumed using the same span around PPZC as for goethite (pK1=6.3, pK2=8.92 with PPZC=7.8) |
