Voltammetric Determination of Trace Amounts of Lead With Novel Graphite/Bleaching Earth Modified Electrode

Modified composite electrodes have gained considerable interest in the detection of heavy metal ions due to their excellent sensitivity, selectivity, stability, and rapid response. Generally, these sensors consist binder, conductive substance, modifier. This study examined into performance a novel modified electrode that used graphite–bleaching earth (BE-MCPE) performed while detecting trace amounts Pb(II) using differential pulse voltammetric technique (DPASV). In order investigate properties BE-MCPE, we employed several analytical techniques, including SEM, SEM-EDX, FTIR, XRD. These techniques were characterize physical, chemical, elemental as well its adsorption capacity, providing comprehensive understanding composition structure. The electrochemical results showed demonstrated superior sensitivity ions, with linear response range 2.10-7 M 10.10-7 M, limit (LOD) 4,89x10-8 mol.L-1, quantification (LOQ) 1,63x10-7 mol.L-1. can achieve sensitive wide wastewater applications.
