Unraveling the role of electrolytes during electrochemical oxidation by differential electrochemical mass spectrometry

Blue Hierarchical TiO2 Nanotube Array for Significantly Enhanced Electrochemical Oxidation Performance and Stability of Tetracycline Degradation

“…Then the degradation process of TC under different Na 2 SO 4 concentrations was analyzed. Compared to the NaNO 3 solution, the Na 2 SO 4 solution with the same conductivity demonstrated a marginal increase in TC degradation ratio, indicating that the prepared anode could activate SO 4 2– in the Na 2 SO 4 solution and then generate SO 4 •– (Figure S3), which was proved in previous works. , As shown in Figure d, the degradation ratios of TC were 90.12%, 90.62%, 91.94%, and 92.44% within 60 min, corresponding to 0.25, 0.50, 0.75, and 1.0 mol L –1 of Na 2 SO 4 solution, respectively. Consistently, the degradation kinetic constant ( k ) also slightly rose from 0.0390 to 0.0431 min –1 (Figure e).…”

Consistently, the degradation kinetic constant (k) also slightly rose from 0.0390 to 0.0431 min −1 (Figure 3e).…”

Demineralization of Oxalic Acid Solutions by Anodic Oxidation in a Stirred Tank Electrochemical Reactor: Experimental and Modeling Study

“…Sulfate ions exhibit electrochemical reactivity and can undergo transformations through charge transfer or •OH radicals, which indicates their noninert nature. In a study by Mostafa et al, it was observed that in the oxidation of oxalic acid within an electrolyte containing sulfate, both the Faradaic current and the ion current associated with CO 2 formation were approximately 30% higher compared with electrolytes containing perchlorate or nitrate. This heightened activity suggested the additional generation of sulfate radicals, which contributed to the oxidation of oxalic acid .…”

“…This heightened activity suggested the additional generation of sulfate radicals, which contributed to the oxidation of oxalic acid. 43 Sulfate radicals, known for their robust oxidative properties and standard reduction potentials comparable with those of •OH radicals, exhibit greater selectivity for oxidation at acidic pH. This highlights their potential involvement in the mineralization process of oxalic acid.…”

“…( 1) which can attack organic pollutants (R) nonselectively, turning them into non-hazardous products or even leading them to complete combustion, as shown in Eq. ( 2) below (do Vale Júnior et al, 2019;Brillas, 2021;Karim et al, 2021;Mostafa et al, 2021).…”
