In situ synthesis of FeOOH-coated trimanganese tetroxide composites catalyst for enhanced degradation of sulfamethoxazole by peroxymonosulfate activation

Effective Activation of Peroxymonosulfate by Oxygen Vacancy Induced Musa Basjoo Biochar to Degrade Sulfamethoxazole: Efficiency and Mechanism

“…Moreover, under the PMS/MBB-800 condition, around a 23-fold enhancement of SMX removal rate constant was observed in comparison to MBB-800 alone. Table S3 and Figure 2 b included the turnover frequency (TOF), which is derived by dividing the catalyst dosage (mg) by the removal rate for SMX degradation (mg h −1 ) in order to provide a more intuitive assessment of the degradation efficiency [ 25 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ]. It was evident that the MBB-800/PMS system demonstrates comparable or even superior performance in degrading SMX compared to the catalysts reported in the literature [ 61 , 62 ].…”

Extraction of antibiotics identified in the EU Watch List 2020 from hospital wastewater using hydrophobic eutectic solvents and terpenoids

“…Due to the lack of data about the possible chronic health effects associated with the longterm ingestion of pharmaceuticals at low concentrations, these compounds are not either regulated or included in the models for the assessment of water quality index [4,6,[18][19][20]]. However, their potential environmental impact and adverse health effects have drawn the attention of health bodies and agencies worldwide.…”

Monodisperse-porous Mn5O8 microspheres as an efficient catalyst for fast degradation of organic pollutants via peroxymonosulfate activation

“…7 Manganese oxide (MnO x ) based heterogeneous catalysts have been reported as promising catalysts for PMS activation due to multiple oxidation states (transformations among Mn(II), Mn(III), and Mn(IV)), low cost and low toxicity when compared with other metal oxide-based heterogeneous catalysts. 8 Recently, many researchers have synthesized different MnO x based heterogeneous catalysts with different chemical states, like MnO 2 , [9][10][11][12][13][14] Mn 2 O 3 , 15,16 Mn 3 O 4 17,18 and mixed oxides, 19 used for the degradation of different organic pollutants via PMS activation. Also, there are some studies in which composite bimetallic oxide-based heterogeneous catalysts were used for the efficient removal of organic pollutants.…”
