Mechanism of bicarbonate enhancing the photodegradation of β-blockers in natural waters

A nano CoFe2O4 entangled CMC/psyllium/RGO (CPRHG/CF)-based hydrogel composite for the adsorption & photocatalytic removal of pharmaceutical effluent: tramadol

“…Although CO 3 is less reactive compared to some other radicals, certain studies have shown its selectivity for compounds with electron-rich moieties, such as aromatic anilines, phenols, and sulfur-containing groups. 62,63 Fortunately, TMD contains electron-rich methoxy groups (-O-CH 3 ) substituted on its benzene ring, as presented in Fig. S1 (ESI †).…”

Indirect photodegradation of ofloxacin in simulated seawater: Important roles of DOM and environmental factors

“…Other environmental factors in seawater also can affect the generation of RIs, thus having an impact on the photodegradation of organic pollutants. It has been demonstrated that NO 3 − , HCO 3 − , salinity, and pH are crucial factors in seawater to influence the indirect photodegradation of organic pollutants (Bai et al, 2018;Wang et al, 2021). NO 3 − can produce •OH through direct photolysis under solar radiation to affect the photodegradation of organic pollutants, and the quantum yield of •OH was affected by pH (Bodrato and Vione, 2014).…”

Sodium Percarbonate Activation by Plasma-Generated Ozone for Catalytic Degradation of Dye Wastewater: Role of Active Species and Degradation Process

“…The generated CO 2− 3 could react with •OH, or HCO 4 − could self-decompose and form •CO 3 − (Equations (16) and (17))[29], which could contribute to organic contaminant degradation. To inspect the role of •CO 3 − , we conducted the experiment with indole (10 6 M −1 S −1 ) present, a known quencher of •CO 3 −[41]. The result is given in Figure5.…”
