Journal ArticleDOI
Persulfate-Based Advanced Oxidation: Critical Assessment of Opportunities and Roadblocks.
TL;DR: This Critical Review comparatively examines the activation mechanisms of peroxymonosulfate and peroxydisulfates and the formation pathways of oxidizing species and the impacts of water parameters and constituents such as pH, background organic matter, halide, phosphate, and carbonate on persulfate-driven chemistry.
Journal ArticleDOI
Chemistry of persulfates in water and wastewater treatment: A review
Stanisław Wacławek,Holger V. Lutze,Klaudiusz Grübel,Vinod V.T. Padil,Miroslav Černík,Dionysios D. Dionysiou +5 more
TL;DR: In this paper, the authors provide an overview of various methods for analysis of persulfate decontamination and their analysis is often prone for interference by other matrix components and hampered by the low stability of peroxydisulfate and peroxymonosulfate in aqueous systems.
Journal ArticleDOI
Production of Sulfate Radical and Hydroxyl Radical by Reaction of Ozone with Peroxymonosulfate: A Novel Advanced Oxidation Process
TL;DR: It is demonstrated that the reaction between the anion of PMS and O3 is primarily responsible for driving O3 consumption with a measured second order rate constant of (2.12 ± 0.03) × 10(4) M(-1) s(-1).
Journal ArticleDOI
Degradation of chlorotriazine pesticides by sulfate radicals and the influence of organic matter.
Holger V. Lutze,Stephanie Bircher,Insa Rapp,Nils Kerlin,Rani Bakkour,Melanie Geisler,Clemens von Sonntag,Clemens von Sonntag,Torsten C. Schmidt +8 more
TL;DR: Atrazine, propazine, and terbuthylazine are chlorotriazine herbicides that have been frequently used in agriculture and thus are potential drinking water contaminants and are degraded more efficiently by sulfate radicals than by hydroxyl radicals.
Journal ArticleDOI
Heat-activated persulfate oxidation of atrazine: Implications for remediation of groundwater contaminated by herbicides
TL;DR: In this paper, heat-activated persulfate could effectively degrade atrazine (ATZ) in water, and complete removal of 50μm ATZ could be obtained after 2-h reaction in the presence of 1mM persulfates under 60°C.

Density‐functional thermochemistry. III. The role of exact exchange
TL;DR: In this article, a semi-empirical exchange correlation functional with local spin density, gradient, and exact exchange terms was proposed. But this functional performed significantly better than previous functionals with gradient corrections only, and fits experimental atomization energies with an impressively small average absolute deviation of 2.4 kcal/mol.
Journal ArticleDOI
Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density
TL;DR: Numerical calculations on a number of atoms, positive ions, and molecules, of both open- and closed-shell type, show that density-functional formulas for the correlation energy and correlation potential give correlation energies within a few percent.

Critical Review of rate constants for reactions of hydrated electrons, hydrogen atoms and hydroxyl radicals (⋅OH/⋅O− in Aqueous Solution
TL;DR: In this article, the rate constants for over 3500 reaction are tabulated, including reaction with molecules, ions and other radicals derived from inorganic and organic solutes, and the corresponding radical anions, ⋅O− and eaq−, have been critically pulse radiolysis, flash photolysis and other methods.
