Peroxymonosulfate Activation by BaTiO3 Piezocatalyst
Catalysts, 2022 Peroxymonosulfate (PMS) plays an important role in the advanced oxidation process for environmental remediation. In this study, barium titanate (BTO) piezocatalyst was selected for the activation of PMS driven by ultrasonic power. The degradation of Rhodamine B (RhB) by BTO single component, PMS single component, and BTO/PMS double components were ...

Activation of Peroxymonosulfate by Subsurface Minerals
Journal of Contaminant Hydrology, 2016In situ chemical oxidation (ISCO) has become a widely used technology for the remediation of soil and groundwater. Although peroxymonosulfate is not a common oxidant source for ISCO, its chemical structure is similar to the ISCO reagents hydrogen peroxide and persulfate, suggesting that peroxymonosulfate may have the beneficial properties of each of ...

Journal of Colloid and Interface Science, 2023
Enhancing the utilization efficiency of oxidant is of great importance for advanced oxidation processes (AOPs). Herein, nitrogen-doped titania dioxide/carbon (NTC7) catalyst was fabricated via pyrolyzing NH2-MIL-125 under nitrogen atmosphere at 700 °C.

Evolution of Singlet Oxygen by Activating Peroxydisulfate and Peroxymonosulfate: A Review [PDF]
International Journal of Environmental Research and Public Health, 2021 Advanced oxidation processes (AOPs) based on peroxydisulfate (PDS) or peroxymonosulfate (PMS) activation have attracted much research attention in the last decade for the degradation of recalcitrant organic contaminants. Sulfate (SO4•−) and hydroxyl (•OH) radicals are most frequently generated from catalytic PDS/PMS decomposition by thermal, base ...

Activation of peroxymonosulfate by bicarbonate and acceleration of the reaction by freezing
Science of The Total Environment, 2021This study demonstrates the positive effects of dissolved bicarbonate and carbonate anions on peroxymonosulfate (PMS) induced oxidation and the remarkable acceleration of the reaction by freezing. More than 90% of the initial 4-chlorophenol (4-CP) decomposed in the frozen case, whereas only less than 20% of the 4-CP was removed in the aqueous case in ...

Spectrochimica Acta Part A: Molecular Spectroscopy, 1985
Both i.r. and Raman spectra of solid anhydrous KHSO5 and KHSO5 · H2O were measured, along with the Raman spectrum of the peroxymonosulfate ion, HSO−5, in aqueous solution. A normal coordinate analysis of the ion was carried out, and the fundamental frequencies and force constants are compared with those of the isoelectronic fluoroxysulfate ion, SO4F−.

The Journal of Chemical Thermodynamics, 1982
Abstract The standard enthalpy of formation at 298.15 K of the aqueous peroxymonosulfate ion, HSO5−, has been determined by reduction of the ion in aqueous HI. The value obtained is ΔHfo(HSO5−, aq) = −(798.4 ± 2.5) kJ·mol−1. This enthalpy was combined with an estimated entropy for the aqueous ion to yield a standard electrode potential of (1.82 ± 0 ...
