| Comment: |
I = 0.003 - 0.1 M; modified TLM: indifferent electrolyte-surface interactions, electrolyte ions accumulate to screen surface charge, but do not form complexes with surface sites; fits are quite good; =Fe(nb)-OH: third, non-copper binding site class (20-60% of the total sites); SSD for weak and non-binding sites were fixed, not fit |
