Advanced oxidative degradation of acetaminophen by carbon catalysts: Radical vs non-radical pathways

Two representative carbon catalysts, granular activated carbon (GAC) and carbon nanotube (CNT) were selected for the degradation of acetaminophen (ACT) by persulfate (PS) activation. In this study, the materials characterization study indicated that the surface functional groups and surface area of the GAC were more abundant and larger, respectively, than the CNT. Whereas the contribution of sp2 and CO groups of the CNT was superior to the GAC;...
