Historical (view previous versions of standard)
This test method covers the determination of inorganic active oxygen in bleaching compounds such as perborates, percarbonates, and peroxides by titration of an acidified aqueous solution with a standard solution of potassium permanganate. Tests shall use reagent grade chemicals, reagent water, potassium permanganate standard solution, sodium oxalate, and sulfuric acid. Well mixed sample shall be titrated according to the procedure indicated in this standard method. Active oxygen weight percent shall be calculated using the given formula.
