TLDR
Experimental results suggest that formation of inner-sphere complexes through the arsonic acid group is the primary mechanism for adsorption of p-ASA/ROX on iron (hydro)oxides and γ-MnO2, while outer-spheres complexation plays a critical role in their adsorbing on α-Al2O3 and kaolinite.About:

Surface complexation of ferrous iron and carbonate on ferrihydrite and the mobilization of arsenic.
TL;DR: Model calculations confirm that sorption of particularly carbonate at common soil and groundwater concentrations reduces the sorption capacity of arsenic on ferrihydrite significantly, a cause for the high concentrations of arsenic in groundwater in Bangladesh.
