Comment: |
PZC obtained by interpolation of the electrophoretic mobilities (0.01% solid in 0.01M NaCl) to zero electrophoretic mobility; pK: literature compilation of experimental values for aluminium oxides [GS84a]: pK1=7.38, pK2=9.09; C from [GS84a] (original [WH80] for g-Al2O3); reactive functional group =AlOH |
