| Comment: |
modified TLM; I = 0.01and 0.1 M; indifferent electrolyte-surface interactions, electrolyte ions accumulate to screen surface charge, but do not form complexes with surface sites; experimental data can be replicated well by assuming three binding sites, data given here are valid for class 2 second site class typically repesented 0.2-0.5% of the total site ; fit with assumption of =FeOCu+ and =FeOCuOH; WSOS/DF=6.8 |
