PROBLEM TO BE SOLVED: To obtain the accurate measured data of the concentration of a treatment agent by suppressing the effect exerted on the measuring precision of a dissolved organic substance in sample water taken in from an aqueous system. SOLUTION: In the measuring method of the concentration of the treatment agent in the aqueous system for chemically reacting the treatment agent C comprising an anionic polymer electrolyte added to the liquid in the aqueous system with a reaction reagent R to form an insoluble substance and measuring the concentration of the treatment agent C by nephelometry, the reaction reagent R and salts S are added to the sample water W<SB>1</SB>taken in from the aqueous system.
