Standard Test Method for Active Oxygen in Bleaching Compounds

Abstract

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.

Scope

1.1 This test method covers the determination of inorganic“ active oxygen” in bleaching compounds such as perborates, percarbonates, and peroxides but not in persulfates or monopersulfates.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Safety Data Sheets (formerly known as Material Safety Data Sheets) are available for reagents and materials. Review them for hazards prior to usage.
