Resting State Functional Connectivity in PTSD Veterans: An EEG Study

Synthesis of different crystallographic FeOOH catalysts for peroxymonosulfate activation towards organic matter degradation

“…This phenomenon is consistent with many other heterogeneous catalytic reactions for the activation of PMS. 39 The increase in PMS concentration within a certain range is conducive for producing more free radicals to attack pollutants. However, too many unreacted PMS in the solution will quench the produced free radicals as shown in the following reaction: 40 SO 4 − ˙ + HSO 5 − → SO 5 − ˙ + HSO 4 − ˙OH + HSO 5 − → SO 5 − ˙ + H 2 O …”

Degradation of recalcitrant organics in landfill concentrated leachate by a microwave-activated peroxydisulfate process

“…It has attracted much attention as a Fenton-like reagent in wastewater treatment since the publication of studies of Anipsitakis and Dionysiou. 22,23 Persulfate has low oxidizing capacity (E 0 ¼ 2.01 V), but aer activation by factors such as such as heat, ultraviolet radiation, ultrasound, microwave (MW) (eqn (1)), and transition metals (eqn (2)), [23][24][25][26][27] it can generate sulfate radical (SO 4 c À ). This radical has a high oxidation potential, i.e., 2.6 V, which is close to that of hydroxyl radical (E 0 ¼ 2.8 V, halflife < 1 s).…”

Treatment of Arsenite‐Contaminated Water by Electrochemical Advanced Oxidation Processes

“…In electrochemical process, iron anode play the role of a coagulant and a catalyst . The reduction and oxidation reactions in electrochemical cell influences the formation of iron species in water medium thereby determining the process function . In electrocoagulation process, iron electrode is used as anode for in‐situ generation of coagulant agents, while in electro‐Fenton process with electro generated hydrogen peroxide; ferrous ion is chemically introduced to the electrochemical cell for the formation of Fenton reagents .…”
