FIELD: analytical chemistry. SUBSTANCE: hydrogen peroxide is titrated with potassium bichromate in the presence of sulfuric acid in aqueous-organic medium, - a mixture of acetone-water taken at the ratio (4-2):1. Absorption of colored complex formed is measured by spectrophotometry method. EFFECT: improved method of assay.
