▎ 摘  要

NOVELTY - Composition comprises a mixture of a corrosion inhibiting compound with a graphene quantum dot comprising a content of the corrosion inhibiting compound covalently bonded to an edge of the graphene quantum dot. USE - The composition is useful for monitoring corrosion inhibitor concentration (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for monitoring corrosion inhibitor concentration, comprising applying a corrosion inhibiting composition to a produced water to form a tagged water source, where the corrosion inhibiting composition comprises a water soluble corrosion inhibiting compound, and a tagged corrosion inhibitor comprising a graphene quantum dot having a content of the corrosion inhibiting compound covalently bonded to it, and the concentration of the corrosion inhibiting composition in the tagged water source is 5-5000 ppm by weight, irradiating the tagged water source with a source of light having a selected first range of wavelengths, and measuring the luminescent emission of the tagged water source at a selected second range of wavelengths, where the measuring is carried out substantially contemporaneously with the irradiating.
