Abstract
Regularities in catalytic oxidation of "Acid chrome dark blue" dye in water solutions are studied under the effect of Fe-montmorillonite catalyst obtained by intercalation of iron polyhydroxocomplexes into the montmorillonite clay from Mukhortalinskoye deposit (Buryatia). An impact of the initial concentrations of reagents, temperatures, and ðÍ on the reaction rate is studied. The outcomes of organic dyes oxidation bear witness to the possibility of practical application of Fe-montmorillonite catalyst in the processes of sewage decontamination from dyes.
