METHOD FOR QUANTITATIVE DETERMINATION OF METHYLPHOSPHONIC ACID DIISOPROPYL ESTER

摘要

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. ^ 3 tbl
