Comment: |
extended TLM; values refer to the hypothetical 1 M standard state; monodentate-mononuclear inner-sphere surface complex; experimental data obtained from [FAYKN13]; 0.01 or 0.1 M NaCl; complexation
constants were determined by simultaneous regression of the sulfate adsorption and ferrihydrite surface charge data |
