Comment: |
average non-electrostatic SC constant for aluminosilicates of 11 curves from [RBMB88], [RBAB91], [AOTKA82], [AMBTS89] and [MSO92]; standard deviation relate to the differences in fitted logK constants from the various batch sorption data sets; 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. |
