Utilizing Electrogenerated Active Chlorine for Enhanced Sanitation in Sports Facilities: Electrochemical Properties and Decontamination Efficacy

Abstract

Background: Electrochemical water treatment technology offers an environmentally friendly solution for sanitation, capable of degrading pollutants through electrode reactions or oxidation without generating secondary pollutants. This technology is particularly suitable for sports environments where high hygiene standards are required to protect athlete health. Methods: This study evaluated the chlorine evolution performance and current efficiency of four types of Dimensionally Stable Anode (DSA) plates (Ru-Ir, Ir[1]Ta, Sn-Sb, Pt) using a custom intermittent electrolytic cell. We monitored the active substances produced during electrolysis, analyzed the composition of the electrolyte, and assessed the efficacy of the generated active chlorine against three compounds analogous to typical military chemical agents (HD, GD, VX) which resemble common environmental toxins. Results: The Ru-Ir (ruthenium-iridium) electrode plate displayed the lowest chlorine evolution potential and the highest current efficiency, indicating superior performance in chlorine generation. The electrolytic cell demonstrated robust on-line oxidation capabilities, not only due to the various valence states of active chlorine but also through the action of intermediate active oxygen free radicals, which contribute to disinfection. The produced active chlorine disinfectant complied with usage standards necessary for neutralizing substances comparable to military-grade chemical agents. Conclusion: The application of electrogenerated active chlorine produced by electrolytic cells shows promise for enhancing sanitation in sports facilities. By utilizing the Ru-Ir electrode plates for chlorine generation, sports facilities can achieve high levels of disinfection, effectively reducing the risk of contamination and ensuring a safe environment for athletes. This study underscores the potential of adapting military-grade decontamination technology for use in maintaining cleanliness in sports and fitness settings, providing a safe and effective method to meet the stringent hygiene requirements necessary in these venues.
