Electrochemical oxidation of bisphenol S with SnO₂-MWCNT electrodes

Bisphenol S (BPS) is a synthetic compound frequently used as an alternative to Bisphenol A (BPA) in the manufacture of various plastics and resins. Its widespread use has led to its detection in environmental samples, raising concerns about its potential endocrine-disrupting effects and toxicity. Recent research shows that BPS can leach from consumer products and accumulate in aquatic ecosystems, posing risks to both aquatic organisms and human health. Electrochemical oxidation of BPS has emerged as a promising approach for its degradation. This study examines the electrochemical oxidation of Bisphenol S utilizing SnO₂-MWCNT (multi-walled carbon nanotubes) electrodes in a galvanostatic regime at different current densities (10, 15 and 20 mA cm⁻²). The main objective of this study was to compare the removal efficiency and energy consumption during the degradation of BPS on various current densities. Experimental results indicated that an increase in current density corresponds to a rise in both removal efficiency and energy consumption. However, this observation highlights the necessity for careful optimization to balance efficiency and energy consumption in real-world applications.
