    13 Document 13.1 Measuring principle 13 Document 13.1 Measuring principle The measuring principle is a voltammetry method using a diamond electrode (BDD (Boron- Doped Diamond) electrode) as the working electrode. Residual chlorine is generally classified into free residual chlorine and combined chlorine, as shown in the figure below, and free chlorine is further classified into chlorine (gas), hypochlor- ous acid (HClO), and hypochlorite ion (ClO ).
  • Page 96 13 Document 13 Document 13 Document 13.1 Measuring principle The ratio of hypochlorous acid and hypochlorite ion changes depending on the pH of the solution as shown in the figure below. Hypochlorous acid is said to have several tens of times high sterilization power than hypochlorite acid ion.
