High-Performance COD Detection of Organic Compound Pollutants using Sulfurized-TiO2/Ti Nanotube Array Photoelectrocatalyst

Electrochemical Performance of Tellurium Oxide on TiO2/Ti Array for Photoelectrocatalytic Chemical Oxygen Demand Sensor Applications

“…This is in accordance with Faraday's law that the value of charge is proportional to concentration, Q = nFVC (Priya & Jeyanthi, 2019;Zini et al, 2020). Overall, the three electrodes showed good performance, this is evidenced by the charge value from the measurement results close to the theoretical charge value (Nurdin, Muzakkar, et al, 2022). The electrode with 0.16% Te concentration is the electrode that has a charge value that is closest to the theoretical charge value of the test sample.…”

“…Then cleaned by soaking in a solution of HF, HNO3 and aquades in a ratio of 1:3:6 for 2 minutes in each solution. In the final stage, TiO2/Ti plate was anodizing at a potential of 25 V in an electrolyte solution containing 87% glycerol, distilled water and 0.27 M NH4F, the same as used in the previous work (Nurdin, Muzakkar, et al, 2022).…”

ZnO-Enhanced Reduced Graphene Oxide Electrodes from Cocoa Shell: Nanoarchitectonics Platform for Photoelectrocatalytic Detection of Methylene Blue

“…This remarkable precision is in accordance with Faraday s law, a fundamental principle in electrochemistry, which states that the amount of charge produced during an electrochemical reaction is directly proportional to the quantity of substance undergoing oxidation or reduction at the electrode. Hence, as the concentration of methylene blue compounds in the solution increases, the charge reception at the electrode also increases 31) .…”

Rapid and Reliable Electrochemical Measurement of Chemical Oxygen Demand Using SnO2–Sb-Based Anodes

“…Owing to their low applied potential required for generating • OH at oxidized Cu­(III) sites and good COD detection, Cu-based anodes are appealing for measuring water samples containing low concentrations of organics . However, Cu-based electrodes should work in alkaline media, and the pH of water samples must be adjusted before COD measurements using alkaline solution. ,, Recently, low-cost and low-toxicity TiO 2 - and Ni-based anodes have been successfully employed to measure COD. − However, because of their narrow linear range and low COD detection accuracy, these anodes must be optimized. Overall, conveniently manufactured and fabricated pollution-free anodes possessing high activity and good stability must be developed for electrochemically measuring COD.…”
