Comment: average non-electrostatic SC constant for aluminosilicates of 4 curves from [NEA94], [LKDA94] and [FWR95]; IS was 0.01, 0.05 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.
