Comment: |
average non-electrostatic SC constant for aluminosilicates of 5 curves from [SEM81] and [NEA94]; standard deviation relate to the differences in fitted logK constants from the various batch sorption data sets; IS was 0.01, 0.1 and 0.5 M; surface complexation to aluminosilicate >SiOH or >AlOH reactive sites is considered equivalent to the reactivity of aluminum oxide and silica reactive sites. |
