摘要
Provided are: a method of measuring the total concentration of oxidizing agents, by which the total concentration can be determined in a single measurement with simple operations even in an evaluation solution containing multiple components such as persulfuric acid, perosulfate and hydrogen peroxide; a simple and inexpensive concentration meter for measuring the total concentration of oxidizing agents; and a sulfuric acid electrolysis device comprising the concentration meter. The method according to the present invention is a method of measuring the total concentration of oxidizing agent(s) in an evaluation solution containing at least one oxidizing agent. The method comprises at least the steps of: heat-treating the evaluation solution at 50 to 135° C.; and detecting hydrogen peroxide in the thus heat-treated evaluation solution.
