FIELD: analytical chemistry, qualitative analysis in various objects. SUBSTANCE: method can be employed for qualitative analysis in various objects, for instance, in sewage of factories manufacturing phthalocyanine paints or utilizing them. Method includes processing of samples by solution of ammonium hydroxide and photometering of obtained solutions with wave length 420 nm and is characterized by speed of determination, sufficiently high accuracy and enables content of phtholocyanine green in presence of phtholocyanine blue with which it is used in industry to win stable greenish-blue shades to be established. EFFECT: increased speed and sufficiently high accuracy of method. 3 tbl |
