Abstract: Systems, methods and devices relating to measuring free chlorine in liquid samples. An enhanced graphite electrode and sensors comprising the same are provided. The enhanced graphite electrode in conjunction with a reference electrode and a counter electrode can be used in a chronoamperometry mode to detect concentrations of free chlorine in liquid samples, especially static liquid samples. The enhanced graphite electrode can also be used in conjunction with a counter/reference electrode in a pulsed amperometric detection mode to detect concentrations of free chlorine in liquid samples, especially static liquid samples.
