| 中文摘要 | The adsorption of H+, Fe2+ and Al3+ from solutions at the gamma-FeOOH electrolyte interface has been investigated. The experimental data could be described by the surface equilibria: p H+ + q = FeOH + r M(m+) = H(p)(=FeOH)(q)M(r)(p + mr)+ and the subsequent intrinsic stability constants beta(s)p,q,r(int): adsorption of H+:log beta(s)-1,1,0(int) = 6.45; log beta(s)-1,1,0(int) = -8.13 adsorption of Al3+:log beta(s)-2,1,1(int) = -2.74; log beta(s)-3,1,1(int) = -9.53 adsorption of Fe2+:log beta(s)-1,1,1(int) = -2.13; log beta(s)-2,1,1(int) = -8.53. These constants were obtained at 298.2 K in a 0.6 mol dm-3 NaCl ionic medium, assuming an electrical double layer of constant capacitance. The optimum values for the surface-site density and specific capacitance are 1.67 sites nm-2 and 2.08 F m-2 respectively. This study supports the earlier presumption of Fe2+ adsorption being involved in the crystal growth of lepidocrocite or in its transformation to goethite or magnetite. Co-adsorption of Fe2 and Co2+ as a basis for manufacturing Co-doped Fe(III) hydroxides is discussed. |
