Degradation of norfloxacin by sulfur-doped iron-cobalt oxides activated perodisulfate: Synergism between free radicals and singlet oxygen

Peroxymonosulfate activation by cobalt-doped ferromanganese magnetic oxides through singlet oxygen and radical pathways for efficient sulfadiazine degradation

“…8d demonstrates that the administration of HA effectively suppresses the degrading impact of SDZ, which can be ascribed to the effect of HA on both the targeted pollutant and the catalyst. HA as a competitor of organic matter itself participates in chemical oxidation reactions, consuming reactive oxides; 41 Moreover, HA is characterized by a substantial presence of phenolic hydroxyl and carboxyl groups. These groups have the ability to adsorb onto the catalyst's surface, leading to the inhibition of SDZ and PMS adsorption in water by the catalyst.…”
