Persulfate activation by modified red mud for the oxidation of antibiotic sulfamethoxazole in water

Persulfate Process Activated by Homogeneous and Heterogeneous Catalysts for Synthetic Olive Mill Wastewater Treatment

“…The result obtained agrees with that obtained by Chueca et al [29,32], which, among the few studies found, focused on the treatment of wastewaters from the agro-food industry by iron-activated PS. Although the result obtained was as expected, the discrepancy between the efficiency of COD removal between pH 5 and the remaining values was unexpected, since it was reported by Ioannidi et al [12] that the SRbAOP has a wide operating range of pH values.…”

“…The hydroxyl radicals react through unselective multi-step pathways, which limits the process efficiency [11][12][13].…”

Peroxymonosulfate activation by tea residue biochar loaded with Fe3O4 for the degradation of tetracycline hydrochloride: performance and reaction mechanism

“…Therefore, as the initial TCH concentration increases, the degradation rate gradually decreases. 46 The decrease in the TCH degradation rate is mainly due to the competition of TCH molecules for the limited amounts of reactive species since the PMS concentration is fixed while the TCH concentration is increased. However, after one hour of reaction, the difference in degradation rate between different systems decreases, and the degradation rate can reach a good result.…”

Effective degradation of COVID-19 related drugs by biochar-supported red mud catalyst activated persulfate process: Mechanism and pathway

“…In recent years, red mud (RM), a kind of iron-rich solid waste generated from aluminum production by the Bayer process, has attracted increasing attention on its utilization as a Fe-based catalyst for persulfate activation ( Du et al, 2020b ; Feng et al, 2016 ; Ioannidi et al, 2020 ; Matthaiou et al, 2018 ; Qian et al, 2016 ). However, the reactivity is greatly limited by the form of Fe species (Fe 2 O 3 ) in red mud.…”
