Abstract
The sorption of ferric and ferrous ions from aqueous solutions on the silica powder,
obtained from colloidal dispersion of silica (silica sol), was studied as a function of their
concentrations and solution pH. The amount of sorbed ferric and ferrous ions increases with
increasing final pH of the solution. The sorption isotherms are of high-affinity type. A sorption
mechanism of ferric and ferrous ions from aqueous solutions on silica is proposed.
