FIELD: chemistry.
SUBSTANCE: method involves the formation of a coloured complex with thiocyanate, measurement of the optical signal at the light absorption maximum of the coloured complex, and an estimate of the content of thiocyanate. As the reaction medium, a polymethacrylate matrix with an immobilized complex of diphenylcarbazole and mercury (II) is used. To assess the content of thiocyanate, the light absorption of the coloured complex at a wavelength of 550 nm is measured or a visual evaluation of the intensity of the colour of the polymer matrix is carried out.
EFFECT: simplifies the method and shortens the measurement time.
