METHOD OF SIMULTANEOUS FRACTIONAL ANALYSIS OF PERACETIC ACID AND HYDROGEN PEROXIDE

摘要

A method of simultaneous fractional determination of peracetic acid and hydrogen peroxide which comprises adding a solution containing peracetic acid and hydrogen peroxide to a pH buffer solution with a pH of 5 to 6 which contains a molybdic acid salt, iodine, and iodide ions and measuring the changes in oxidation-reduction potential caused by the reactions of the peracetic acid and hydrogen peroxide with the iodide ions. Thus, the concentrations of peracetic acid and hydrogen peroxide in a mixture of these can be easily, continuously, and simultaneously measured fractionally.
