FIELD: medicine.
SUBSTANCE: oil-in-water microemulsion for a fluorimetry method of quantitative analysis of flumequine contains in an aqueous phase an analysed solution, an acetate-ammoni buffer solution pH 7.2-8.0, terbium salt Tb(NO3)3·5H2O; a surfactant - sodium tetradecyl sulphate, a cosolvent representing n-pentanol, with 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline, in an oil phase - n-octane. The ingredients of the microemulsion are taken in the following proportions: oil phase - 15-30 wt %; sodium tetradecyl sulphate - 7-8 wt %; cosolvent with 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline - 14-15 wt %; water phase - 46-63 wt %.
EFFECT: invention allows analysing flumequine in muscular tissues, blood serum and foods.
