Enhanced degradation of clothianidin in peroxymonosulfate/catalyst system via core-shell FeMn @ N-C and phosphate surrounding

Construction of a Z-scheme g-C3N4/NBGO/BiVO4 heterostructure with visible-light driven photocatalytic degradation of tetracycline: efficiency, reaction pathway and mechanism

“…Tetracycline (TC) is a typical antibiotic used to kill pathogenic bacteria in humans and animals, and has been widely used against commonly occurring infections of the skin and other organs. 1–7 Large amounts of wastewater containing antibiotics are directly discharged into water sources, which poses a massive threat to human health and causes serious environmental problems. 7–11 Thus, it is imperative to explore new control methods and water treatment technologies for removing TC from the water environment.…”

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

“…38 These ndings were in good agreement with previous studies that the degradation efficiency of activated persulfate continuously increases because the increase in Fe 3 O 4 @T-BC dosage might provide more SO 4 À c in the activated system to participate and accelerate the degradation of TCH. 39 3.3.3 Effect of PMS concentration. Similarly, the degradation of TCH as the PMS concentration increased from 0.5 g L À1 to 2.0 g L À1 was studied (Fig.…”

Activation of Peracetic Acid with Lanthanum Cobaltite Perovskite for Sulfamethoxazole Degradation under a Neutral pH: The Contribution of Organic Radicals

“…•− ). They are usually generated through the homogeneous cleavage of the peroxide bond in inorganic peroxides, such as hydrogen peroxide (H 2 O 2 ), peroxydisulfate (PDS) and peroxymonosulfate (PMS) [9]. The inorganic radicals possess high oxidation potential (E 0 = 2.5-3.1 V for SO 4…”

“…The commonly used AOPs are generally based on the in situ generation of highly reactive inorganic radicals, such as the hydroxyl radical (HO • ) and the sulfate radical (SO 4 •− ). They are usually generated through the homogeneous cleavage of the peroxide bond in inorganic peroxides, such as hydrogen peroxide (H 2 O 2 ), peroxydisulfate (PDS) and peroxymonosulfate (PMS) [ 9 ]. The inorganic radicals possess high oxidation potential (E 0 = 2.5–3.1 V for SO 4 •- and E 0 = 1.9–2.7 V for HO • ) [ 10 ] and thus can effectively destruct a wide range of organic contaminants with the second-order rate constants ranging from 10 5 to 10 9 M −1 s −1 for SO 4 •− [ 11 ] and from 10 7 to 10 10 M −1 s −1 for HO • [ 12 ].…”
