NOVELTY - Electrochemical detection of capecitabine in aqueous solution containing water-emerging pollutants, involves preparing a working electrode comprising an active cylinder, by casting a homogeneous paste comprising copper(I) metallomesogen, carbon nanotubes and graphene, in a paraffin oil, in a support cylinder comprising a plastic material chemically-inert to the aqueous solution, placing the working electrode in a classic system with three electrodes immersed in a vessel comprising the aqueous solution, connected to a potentiostat controlled by a computer for application of electric potential, performing cathodic reduction of ordered complex of copper(II) capecitabine to copper(I) with the release of capecitabine, and generating an electrochemical response through cathodic reduction of capecitabine in an alkaline environment, corresponding to the concentration of capecitabine in the aqueous solution, during scanning from anodic to cathodic by differential pulse voltammetry. USE - Electrochemical detection of capecitabine in aqueous solution containing water-emerging pollutants. DETAILED DESCRIPTION - Electrochemical detection of capecitabine in aqueous solution containing water-emerging pollutants, involves preparing a working electrode comprising an active cylinder, by casting a homogeneous paste comprising copper(I) metallomesogen, carbon nanotubes and graphene in a mass ratio of 12.5/1/1/6, in a paraffin oil, in a support cylinder comprising a plastic material chemically-inert to the aqueous solution, and including a copper wire having one end embedded in the paste, and other end which protrudes outside the support cylinder, at the closed side, forming a disc representing an electroactive portion of the electrode acting with the aqueous solution, at the open side of the support cylinder, and on the front side of the active cylinder, placing the working electrode in a classic system with three electrodes immersed in a vessel comprising the aqueous solution, connected to a potentiostat controlled by a computer for application of electric potential necessary for each stage of the detection process, performing cathodic reduction of ordered complex of copper(II) capecitabine to copper(I) with the release of capecitabine, and generating an electrochemical response through cathodic reduction of capecitabine in an alkaline environment, corresponding to the concentration of capecitabine in the aqueous solution, during scanning from anodic to cathodic by differential pulse voltammetry.
