Effectiveness of Granular Activated Carbon for Removal of Sulfamethoxazole during Ozonation
Abstract: Initial experiments were performed to screen a suitable catalyst for catalytic ozonation of sulfamethoxazole (SMX). Among catalysts investigated such as CeO2, MnO2, CeO2/MnO2, and GAC. The GAC catalyst was found appropriate for further study because it adsorbed more SMX … Continue reading
