Minerals as Potential Catalysts in Heterogeneous Catalytic Ozonation: A Kinetic Study of p-CBA Degradation in Aqueous Solutions at pH 7

This study examines the removal of p-CBA via application heterogeneous catalytic ozonation in presence 13 minerals. The solids were used as raw materials or after hydrophilic/hydrophobic modification. optimal minerals zeolite, calcite, dolomite, and thermally treated talc. kinetic showed that decomposition ozone followed a first-order model for all systems, whereas depended on applied. degradation second-order model, while non-catalytic materials; abatement was best agreement with pseudo-second-order single ozonation.
