The 2 μm fraction of Wyoming clay rich in montmorillonite was pillared with aluminum. Obtained pillared clay was impregnated with different cobalt loadings using the incipient wetness impregnation method followed by calcination at 450 °C. The obtained materials were previously fully characterized. The synthesized materials were investigated as catalysts in catalytic oxidation of organic water pollutant, tartrazine, in the presence of Oxone®. Oxone® was a precursor of sulfate anion radicals. The effect of the different cobalt loadings on the reaction kinetics was investigated. The pseudo-first order kinetic model was found to be the most appropriate to fit the experimental data of all investigated catalysts under defined experimental conditions. The presence of Co3O4 as defined crystalline phase reduces the efficiency of cobalt-supported aluminum pillared clay in Oxone® activation and consequently oxidative tartrazine degradation.
