Abstract
Sorption properties with respect to the chromate ions of ferro- and alumogels prepared from Fe(III) and aluminum sulfates, and the composition of oxyhydroxides (OH), are studied. It is determined that the sorption values of chromate ions on ferrogels and alumogels (with NaCl) are notably higher than those on OH prepared from other precursors. It is shown that the sorption of CrO42− on alumogels with Na2SO4 is almost completely inhibited. It is found that gels retain substantial amounts of sulfate ions during precipitation from precursor solutions, while alumogels retain substantially more than ferrogels. The sorption of SO4-gels is explained from the viewpoint of their composition and interaction with Na2SO4 solution. The competitive sorption of chromate and phosphate ions is studied and it is demonstrated that phosphate ions completely inhibit the sorption of chromate ions at comparable concentrations.
