Residual chlorine measuring method and residual chlorine measuring apparatus |
| abstract |
Provided are a method and apparatus for measuring free residual chlorine concentration that is accurate and simple, which can obtain objective measurement results without using any harmful reagents, and without being affected by the potential window. Provided are a method and apparatus for measuring residual chlorine, in which a conductive diamond electrode is used; and a current value is measured when the potential of the conductive diamond electrode against a silver/silver chloride electrode is set to a potential in the range of from 0 V to +1.6 V and the residual chlorine concentration based on hypochlorite ion is calculated, and a current value is measured when the potential of the conductive diamond electrode against a silver/silver chloride electrode is set to a potential in the range of from +0.4 V to -1.0 V and the residual chlorine concentration based on hypochlorous acid is calculated; and the calculated residual chlorine concentration based on hypochlorite ion and the calculated residual chlorine concentration based on hypochlorous acid are added to make the total residual chlorine concentration. Further provided are an apparatus and method comprising a temperature measuring unit and/or a pH measuring unit. |
