Electrochemical Determination of a Free Chlorine Residual Using Cathodic Potential‐Step Chronocoulometry |
|
| Abstract: | The cathodic reaction of chlorine residual (CR) combined with anodic pre‐electrolysis enables the quantification of CR as a gaseous chlorine. Potential‐step chronocoulometry was successfully applied to extend the CR detection range. |
| Keywords: | Chlorine residual Potential‐step chronocoulometry Calibration plot |
