Degradation of pentachlorophenol in peroxymonosulfate/heat system: Kinetics, mechanism, and theoretical calculations

Intercalation of Well‐Dispersed Fe2O3 with SnO2 toward Durable Peroxymonosulfate Activation to Eliminate Antibiotics: Performance and Mechanism

“…[41] In addition, * SO 4 À reacted with OH À to form * OH, and the selfreaction of * OH can produce H 2 O 2 (Eqs. (7,8)). [42] * O 2 À could be obtained via the dissociation of * HO 2 .…”

“…[7] It is generally believed that PMS can be activated by thermal, ultraviolet, microwave and transition metal methods. [8][9][10][11] Transition metal materials, including transition metal ions (Fe 2 + , Mn 2 + and Co 2 + ) and metal oxides (Co 3 O 4 , CoFe 2 O 4 and MnO 2 ) were considered as promising alternatives to activate PMS because of the advantages of high efficiency, low cost and convenience. [12,13] Although transition metal based catalysts can active PMS both in heterogeneous and homogeneous systems, more efforts have been focused on constructing heterogeneous system due to its virtues of reusability and alleviation secondary pollution caused by metal.…”

“…Moreover, peroxymonosulfate (PMS)‐based AOPs displayed excellent performance for degradation refractory organics due to generate strong active radical species of sulfate radicals (⋅SO 4 − ) with high redox potential and longer half‐life [7] . It is generally believed that PMS can be activated by thermal, ultraviolet, microwave and transition metal methods [8–11] …”

A highly dispersed magnetic polymetallic catalyst to activate peroxymonosulfate for the degradation of organic pollutants in wastewater

“…The typical treatment technologies for antibiotic residues in wastewater include adsorption, 7 photocatalysis, 8 electrochemistry, 9 microbial degradation 10 and advanced oxidation processes (AOPs). 11 Among them, AOPs involving the production of highly reactive oxygen species (ROS) are considered as the most effective and promising technical methods for the treatment of organic pollutants due to their fast reaction speed, easy operation and no secondary pollution. 12 Recently, sulfate radical (SO 4 ˙ − )-based AOPs have attracted increasing attention since they show great potential as rapid and effective treatment methods for persistent organic compound removal.…”

Performance and Kinetics of BPA Degradation Initiated by Powdered Iron (or Ferrous Sulfate) and Persulfate in Aqueous Solutions

“…Oxidants (hydrogen peroxide [13], ozone [14], persulfate (PS) [15], and peroxymonosulfate [16]) can be used as precursors to generate free radicals with the help of all kinds of energies or materials [17]. The means of activation can be ultraviolet light (UV) [18], heat [19], microwaves (MW) [20], ultrasound (US) [21], heavy metals (Fe [22], Co [23], Cu [24], Mn [25]), and carbon materials [26,27]. Among the four oxidants mentioned above, PS is favored by researchers because of its stable nature and ease of transport and storage [28].…”
