Effect of Inorganic Salt Mixtures on Phenol Mineralization by Photo-Fenton-Analysis via an Experimental Design

Enhanced Water Purification Efficiency Induced by Trace H2O2 on the Electron Distribution-Polarized Unequilibrium Surface of CuS/ZnO Nanosheets

“…By constructing electron-rich/poor microdomains on the CS/ZO NSs surface, Cu centers did not directly participate in reaction processes but only acted in electron aggregation, which effectively avoided the strong dependence of the reactivity of conventional metal-containing catalysts on the pH of the reaction system. The presence of different salts in wastewater often causes a sudden decrease in the catalytic activity of the reaction system . As shown in Figure e, the degradation effects of CIP in different salt solutions were investigated by adding SO 4 2– , Cl – , and HCO 3 – in CS/ZO NSs/H 2 O 2 system.…”

“…The presence of different salts in wastewater often causes a sudden decrease in the catalytic activity of the reaction system. 36 As shown in Figure 3e, the degradation effects of CIP in different salt solutions were investigated by adding SO 4 2− , Cl − , and HCO 3 − in CS/ZO NSs/H 2 O 2 system. The results showed that CS/ZO NSs exhibited excellent degradation performance with a variety of anionic interfering factors, and the degradation rate of CIP reached 100% in 60 min, indicating the wide adaptability of CS/ZO NSs/H 2 O 2 system.…”

Direct Blue 71 removal by electrocoagulation sludge recycling in photo-Fenton process: response surface modeling and optimization

“…Fenton-based processes (Fenton, electro-Fenton, photo-Fenton (PF), and sonoFenton) are viable processes in which iron plays the role of catalyst and reacts with hydrogen peroxide to form the strong destructive agent; the hydroxyl radical [11][12][13]. Initially, decomposition of hydrogen peroxide by the catalytic function of iron in acidic pH brings about the generation of hydroxyl radical (Fenton reaction) [14][15][16][17]:…”

Effect of Salinity on UVA-Vis Light Driven Photo-Fenton Process at Acidic and Circumneutral pH

“…On one side, the presence of some anions such as phosphate, chloride or carbonate have been described to inhibit photo-Fenton [7]. While the first one forms iron phosphate, a very stable and insoluble salt that decreases iron availability, the presence of which is incompatible with Fenton chemistry [8], the other ions interact with iron, modifying the Fenton mechanism and generating less reactive species that limit but do not stop the Fenton process [9][10][11].…”
