- W910392654 abstract "They are offered chemical test-methods of aromatic amines and phenols determination founded on chemisorptions planar chromatography. Immobile phases are chemical immobilized on cellulose paper 1-naphtyl amine and о-tolidine. An analyzed solution serves as a mobile phase. The chemical immobilized 1-naphtyl amine is the azo component after diazotization by nitrite at the determination of aromatic amines. The immobilized о-tolidine is used at the determination of the phenols by oxidizing condensation at pH 10 in presence of a potassium hexacyanoferrate (III) with colored indophenols formation. A length of test-strips colored zone is an analytical signal. Test-strips stuck in a polymeric film. A range of determined concentrations are 0.05-200 mg/l (test-strips) and 0.005-10 mg/l (test-device) for aromatic amines and 0.1-200 mg/l (test-strips) and 0.01-10 (test-device) for phenols. A relative standard deviation of results does not exceed 0.3 using test-device and 0.12 for test-strips. Duration of the analysis does not exceed 30 mines." @default.
