| Comment: |
PZC obtained by interpolation of the electrophoretic mobilities (0.01% solid in 0.01M NaCl) to zero electrophoretic mobility; SSD recommended by [DK90] for natural materials; pK: literature [S89a,b] for g-Al2O3; C fixed , values considered optimum for goethite by [ZS90a]; reactive functional group =AlOH |
