Comment: |
average non-electrostatic SC constant for aluminosilicates of 4 curves from [RBAB91], [AOTKA82] and [S83c]; IS was 0.01 and 0.1 M; surface complexation to aluminosilicate >SiOH or >AlOH reactive sites is considered equivalent to the reactivity of aluminum oxide and silica reactive sites. |
