Significantly enhanced base activation of peroxymonosulfate by polyphosphates: Kinetics and mechanism

Evolution of Singlet Oxygen by Activating Peroxydisulfate and Peroxymonosulfate: A Review

“…•− as indicated by Equation ( 5) [46]. It was worth noting that in the studies from Qi [45] and Lou [47], the addition of p-BQ completely inhibited the oxidation reaction in the PMS/base system. But Zhou's report pointed out that p-BQ could effectively activate PMS to generate 1 O 2 under alkaline conditions [41].…”

Cu@Co-MOFs as a novel catalyst of peroxymonosulfate for the efficient removal of methylene blue

“…The concentration of PMS was determined by spectrophotometric determination with iodometric titration. 33 The leaching metal ions (including copper ion and cobalt ion) in reaction solutions and metallic elements in Cu@Co-MOFs structure were measured using an inductively coupled plasma-atomic emission spectrometer (ICP-AES, PE OPTIMA 2100DV). The mineralization of MB was established on the basis of the total organic carbon (TOC) content, performed using a TOC analyzer (Shimadzu) aer the sample was quenched by 2 M sodium thiosulfate.…”

Both degradation and AOX accumulation are significantly enhanced in UV/peroxymonosulfate/4-chlorophenol/Cl− system: two sides of the same coin?

“…Recently sulfate radical-based Advanced Oxidation Processes (AOPs) are attracting much attention in degrading recalcitrant organic pollutants due to its strong oxidizing capacity (E ¼ 2.5-3.1 V versus NHE) and longer half-time (30-40 ps) of sulfate radical (SO 4 c À ). 1 Peroxymonosulfate (PMS) is known as an efficient precursor of SO 4 c À production, with assistance of transition metals, [2][3][4][5] heat, 6,7 base, 8,9 ultrasound, 10 carbon catalysts, 11,12 microwave 13 and ultraviolet (UV). [14][15][16] Upon the cleavage of the peroxo bond, PMS photolyzed by UV was suggested to produce SO 4 c À and cOH in a benign and economic way.…”
