In this study, we have constructed a novel voltammetric sensor based on montmorillonite clay (MMT) incorporated with CeO2 nanoparticles using a composite graphite paste electrode as a cross linker (MMT-CeO2NPs/GPG-PE) for the trace determination of tadalafil (TAD) drug. The characterization of CeO2 nanoparticles has been conducted using various analytical techniques, including X-ray diffraction, transmission electron microscopy, and high-resolution transmission electron microscopy. The morphology of the composite of CPG and MMT-CeO2NPs/CPG was elucidated through scanning electron microscopy (SEM). The newly developed sensor (MMT-CeO2NPs/CPG-PE) exhibited remarkable efficiency towards TAD oxidation using adsorptive stripping square-wave voltammetry (AdS-SWV) in Mcllvaine buffer solution (pH 8.0). A highly selective and sensitive method for TAD detection has been successfully …
