Carbon‐Based Electrochemical‐Free Chlorine Sensors

Sodium hypochlorite is a widely used additive in water to disinfect and remove any disease-causing bacteria that can be found sources of water, wash contaminants from meats, fruits, vegetables. Many free chlorine sensors exist which monitor levels such as the use colorimetric or electrochemical methods, ensuring within safe regulated levels. However sensing methods are irreversible often toxic compounds, sensors, although reversible, made with materials not suitable near drinking food products. By developing using alternative around This review article discusses various electrochemical-free carbon-based resulting biodegradable, relatively inert, resilient presence harsh chemicals, making them still maintain competitive performance parameters. showcases some recent progress, importance, preconditions, future needs potentials sensors.
