The substitution of foreign metals for iron in goethite (α-FeOOH) contributes to the change of adsorptive properties for metal ions, CuII, PbII, and ZnII, in aqueous solutions. Selective removal of PbII from low-pH solutions was enhanced by the addition of Mn in the synthetic process for Mn-substituted goethite particles. This enhancement was caused by the formation of specific surface sites for the selective adsorption.
