Activation of peroxymonosulfate by natural pyrite for effective degradation of 2,4,6-trichlorophenol in water: Efficiency, degradation mechanism and toxicity evaluation

Contact-Electro-Catalysis for the Degradation of Pentachlorophenol Using Inert Fluorinated Ethylene Propylene Powders

“…With NO 3 − and HCO 3 − , the removal efficiency of PCP dropped by 28.8 and 40.7%, respectively. This reduction is attributed to NO 3 − and HCO 3 − reacting with • OH to form radicals (NO 3 • and CO 3 •− ) with lower oxidation potentials, , diminishing the system’s reactivity and hindering PCP degradation. Notably, HCO 3 − shows a more pronounced inhibitory effect than NO 3 − .…”

Study on the Migration and Release of Sulfur during the Oxidizing Roasting of High-Sulfur Iron Ore

“…Furthermore, the stability of the adsorption configuration at different adsorption sites is analyzed in terms of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) (∆E = E LUMO − E HOMO ) [28]. By comparing the ∆E data in Figure 11e-h, it is found that the stability is ranked in order from largest to smallest: O-top > bridge > hollow > Ca-top.…”

“…In recent years, theoretical calculations such as density functional theory (DFT) have been widely applied to deeply understand the reaction mechanism [26]. For instance, some researchers have used DFT calculation to accurately predict adsorption energy, electron transfer and stability, among other features [27,28]. Shen et al evaluated the O-top position as the best adsorption site for CO 2 on the surface of CaO (100) by using DFT calculation [29].…”
