FIELD: analytical chemistry.
SUBSTANCE: quantitative determination of methylphosphonic acid diisopropyl ester is carried out using 15% hydrogen peroxide solution in weakly alkaline medium (pH = 7-8) and 2.5% acetone solution of o-tolidine as an aromatic amine. Method provides improving the main metrological indices of method and enhancing output in carrying out mass analysis of analyzed samples by 3-4 times.
EFFECT: improved assay method.
