Popis: | We studied the effect of the concentration of copper ions on the absorption spectrum of Rhodamine B in molecular form in an alcohol solution and immobilized in a polymer hydrogel film. The system is sensitive to the presence of copper ions at a concentration of 0.1 mg/L, which is sufficient for practical use. The insolubility of Rhodamine B in water during its immobilization in the volume of a photopolymerizable hydrogel film makes it possible to create a chemosensor that is stable at long exposures and is capable of sensing ultralow concentrations of impurities. |
