The dissolution of goethite and other iron oxides is kinetically controlled by the detachment of an Fe center from the surface. Surface protonation and surface complex formation with ligands are reaction steps preceding the detachment. The dissolution rate is enhanced markedly by oxalate which can form bidentate surface chelates with an Fe center in the oxide surface. An additional catalytic effect is observed under reducing conditions. The electron transfer from the reductant to the surface Fe(III) center precedes the detachment step. This may occur either by direct reduction, subsequent to the adsorption of reductants, or, indirectly by electron transfer from dissolved Fe(II) ions which are generated by the same reductants in solution.
