The critical concerns regarding hazardous organic dyes, which cause significant harm to human health and environmental sustainability, require immediate attention. This study demonstrates the development of an innovative disposable electrochemical sensor that employs thiosulfate-modified graphitic carbon nitride (gC3N4-S2O3) nanosheets as class-selective cost-efficient flexible plastic electrodes for remote, handheld monitoring cationic dyes─a class perilous water-soluble pollutants. is capable detecting several such methylene blue (MB), rhodamine B (RhB), thionine (Th), simultaneously in drinking water. Modified gC3N4-S2O3 were produced using a straightforward sonochemical-assisted method, followed by thermal condensation treatment. material characterized Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), impedance spectroscopy (EIS), cyclic voltammetry (CV), differential pulse (DPV). DPV measurements span wide range dye concentrations, ranging from 1 nM mM. Under optimized conditions, exhibits excellent performance, with picomolar limits detection (LOD), i.e., 118 pM Th, 161 RhB, 209 MB, respectively. utilizes electrostatic interactions distinguish between anionic dyes dyes. also enhanced capability detect solutions, complex mixtures, water samples, indicating minimal interference ionic species inherently present work highlights potential sensors application remediation environment.
