3 Method Summary
Under acidic conditions, titrate the hydrogen peroxide in sample with potassium permanganate standard volumetric solution, and then calculate the content of hydrogen peroxide; determine the content of all peroxides (peroxyacetic acid and hydrogen peroxide) in sample with indirect iodometry, and then deduct the amount of hydrogen peroxide to obtain the content of peroxyacetic acid. The reaction formulas are as follows:
