- Аннотация: Samples of a carbon–mineral catalyst based on natural clay and tire crumb for the oxidativedecomposition of nonionic surfactants (NSes) with hydrogen peroxide in wastewater have been developedand studied. The iron content in the samples has been varied in a range of 2.3–3.9 wt %. The effect of thepyrolysis temperature varied for the samples in a range of 350–800°C on changes in their textural characteristics, the number and type of acid sites on the surface, and the ζ-potential (zeta potential) of colloidal systems based on the synthesized samples has been studied. Using model solutions under steady-state anddynamic conditions, the effect of the pyrolysis temperature used for the samples on their catalytic propertiesin the oxidative decomposition of H2O2 and the neonol AF 9-10 NS with hydrogen peroxide has been studied.The best result in the oxidation of neonol AF 9-10 with hydrogen peroxide has been obtained in the presenceof a carbon–mineral catalyst sample calcined at 650°C.
