Ferrous iron sorption by hydrous metal oxides

Adsorption and surface oxidation of Fe(II) on metal (hydr)oxides

“…The adsorption of Fe(II) by TiO 2 (Degussa P25) has been studied by Nano and Strathmann (2006). The adsorption data are shown in Fig.…”

“…All data points are of Nano and Strathmann (2006). The lines are calculated with the CD model using the parameter set of Table 1.…”

“…In this approach, we assume that the adsorbed Fe(II) will distribute the charge equally over its ligands, i.e. equal Fe-O Table 3 Location of ion charge and affinity constants used to describe the experimental charging behavior (Klebanov et al, 2001) and the Fe(II) adsorption (Nano and Strathmann, 2006) Nano and Strathmann (2006). The lines are calculated with the CD model using the parameter set of Table 3. distances.…”

“…Recently, (Nano and Strathmann, 2006) have measured the Fe(II) binding to TiO 2 and boehmite (c-AlOOH) in NaCl and (Dixit and Hering, 2006) measured it recently for goethite (a-FeOOH). As will be discussed in this paper, interpretation of these data suggests that the Fe(II) adsorption behavior does not only depend on the types of surface sites that are involved in the binding, but that the Fe(II) binding may also depend on the presence of Fe(III) as component of the mineral structure.…”

Effects of dissolved organic matter on adsorbed Fe(II) reactivity for the reduction of 2-nitrophenol in TiO2 suspensions

“…Negative and positive shifts in E P indicate enhancement and inhibition of the redox reactivity, respectively, from a thermodynamic perspective (Nano and Strathmann, 2006;Li et al, 2009;Tao et al, 2009Tao et al, , 2010.…”
