Sažetak
The paper examines the impact of different types of zeolite supports on the activity and stability of the Cu/ZSM5, Cu/Y and Cu/X catalyzers used in phenolic (model) wastewater treatment by means of hydrogen peroxide. The catalyzers were prepared by means of ion exchange of the commercial ZSM5, Y and X zeolite. The catalyzer characterization included x-ray powder diffraction (XRD), scanning electron microscope (SEM) micrography), infrared spectroscopy (FTIR), elementary analysis (AAS) and the determination of specific surface by the standard BET method. The reaction was conducted in a batch reactor at the atmospheric pressure, different temperatures (323 K - 353 K), constant concentration of phenol (0.01 mol dm-3) and hydrogen peroxide (0.1 mol dm-3) and catalyzer mass (0,5 g dm-3). The catalyzer efficiency was monitored by means of phenol conversion, total organic carbon and copper removal from the support. It was determined that the Cu/X catalyzer is more active and stable than the Cu/Y and Cu/ZSM5 catalyzers and that it is suitable for phenolic wastewater treatment at mild reaction conditions.
