LUMINESCENT SENSOR FOR CONCENTRATION OF HEAVY METAL IONS IN WATER AND METHOD OF USING IT Russian patent published in 2019 - IPC G01N21/64 B82Y40/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment and concerns a luminescent sensor for determination of heavy metal ions concentration in water. Sensor includes a glass plate on which carbon points (C-points) produced by autoclavable synthesis are applied, which are coated with an aminoethylaminopropyl isobutyl of polyhedral oligomeric silsesquioxane (POS). When the sensor is immersed in a water sample, divalent ions of heavy metals are bound to the surface of C-points in the POS shell. Presence and concentration of heavy metal ions in the sample is determined from the degree of change of luminescence intensity compared to the sensor luminescence previously fixed before dropping into the solution.

EFFECT: technical result consists in simplification of the manufacturing process, longer service life and high sensitivity of the sensor.
