METHOD OF CONTROLLING OXIDIZING AGENT CONCENTRATION, METHOD OF CONTROLLING WATER BASED TREATING AGENT CONCENTRATION USING THE CONTROL METHOD, AND METHOD OF STERILIZING WATER BASE

摘要

PROBLEM TO BE SOLVED: To provide a method of precisely controlling concentration of an oxidizing agent in a water base.

SOLUTION: The method of controlling the concentration of the oxidizing agent in the water base includes at least: performing a first natural potential measuring step of measuring the natural potential of a metal dipped in the water base; and performing an oxidizing agent generating step of generating the oxidizing agent in the water base. The natural potential of the metal has a positive correlation with the concentration of the oxidizing agent and then, the concentration of the oxidizing agent is controllable in a prescribed range by measuring the natural potential of the metal and keeping the natural potential constant.
