FLUORESCENT COMPOUND FOR WATER TREATMENT AND METHOD OF USE THEREOF Russian patent published in 2021 - IPC C02F1/52 C02F1/56 C02F1/68 C09K11/06 C09K11/65 

FIELD: chemistry.

SUBSTANCE: invention relates to compounds or polymers for treatment of a water source labeled with a graphene quantum dot and to methods for manufacture and use thereof. Invention also relates to labeled compositions comprising industrial water source treatment compounds or polymers combined with a water source treatment compound or polymer labeled with a graphene quantum dot. Labeled materials are specially designed to fluoresce at wavelengths minimally corresponding with natural or "background" fluorescence of irradiated materials in industrial water sources, which allows for quantitative assessment of a concentration of the compound for water source treatment or the polymer in situ (directly in reaction system) by irradiation and measurement of fluorescence in the water source containing a labeled compound or a labeled polymer for water source treatment.

EFFECT: methods of fluorescence measurement are similarly applicable for quantitative measurement of mixtures of labeled or unlabeled compounds or polymers for water source treatment present in an industrial water source.
