    One resilient element that is frequently utilized in many manufacturing operations is lead. Because of its enduring nature, it can linger in the atmosphere for quite a while and is harmful to the functioning of biological systems. Mining operations, along with incineration, are the main sources of copper release. As your liver is the first organ to access copper accumulation when it enters the bloodstream, chronic copper poisoning primarily affects it. The supposed advantages of electrochemical sensing are the simplicity of the apparatus, the extreme sensitivity and robust specificity of the test, mobility, and the ability to analyze the target analyte on-site. A nanocomposite of UiO-66-NH2@Ppy NWs@CoFe2O4 was prepared to determine trace amounts of copper and lead ions in water. The atomic structure and physicochemical properties of the prepared material were examined using XRD. The electrochemical behavior of the GCE modified with UiO-66-NH2@Ppy-NWs@CoFe2O4 was studied by means of cyclic voltammetry (CV). It was demonstrated that, with the UiO-66-NH2@Ppy NWs@CoFe2O4, Pb2+ and Cu2+ could be sensed via differential pulse voltammetry (DPV). As the concentration increased from 10 to 100 nM, a substantial linear response was achieved, with a lower limit of detection. The high sensitivity of the UiO-66-NH2@Ppy-NWs@CoFe2O4/GCE towards the electroanalytical applications marked its use for real-world applications in its as-prepared state.
