| titleOfInvention | Residual chlorine measuring method and residual chlorine measuring device |
| abstract | An object of the present invention is to provide an accurate and simple method and apparatus for measuring the concentration of free residual chlorine, which can obtain an objective measurement result without using a harmful reagent, is not affected by a potential window, and is simple. Using a conductive diamond electrode, measure the current value when the potential of the conductive diamond electrode with respect to the silver / silver chloride electrode is set to a potential in the range of 0 V to +1.6 V, and measure the residual chlorine based on hypochlorite ion. Calculate the concentration, measure the current value when the potential of the conductive diamond electrode with respect to the silver / silver chloride electrode is within the range of + 0.4V to -1.0V, and determine the residual chlorine concentration based on hypochlorous acid. Provided is a method and apparatus for measuring residual chlorine, in which a calculated residual chlorine concentration based on hypochlorite ion and a calculated residual chlorine concentration based on hypochlorous acid are added to obtain a total residual chlorine concentration. I do. Further, an apparatus and a method having a temperature measurement unit and / or a pH measurement unit are provided. |
