Catalytic ozonation for removal of antibiotic oxy-tetracycline using zinc oxide nanoparticles
Applied Water Science, 2021 The traditional wastewater treatment plants are mostly not designed to deal with polar micropollutants such as pharmaceuticals. Therefore, antibiotics must be completely removed before their emission to ecosystems. Catalytic ozonation is used to increase
