There are many different species of mercury in the environment, and these species bio-amplify and become methylated to become organo-Hg species. Using FeCoMOF/PANI-NH2 as the starting substrate, we created a novel electrochemical technique called differential pulse voltammetry (DPV) for the quick screening of free Hg+2 in water on a metal-organic framework (MOF) platform. Using bimetallic MOF structures incorporate on polyaniline surface that enhance the stability and conductivity of composite. To improve Hg 2 + detection performance, FeCoMOF/PANI-NH2 nanocomposites were added to the GCE. The conductivity and sensitivity of the FeCoMOF/PANI-NH2/GCE was higher than that of pure FeCoMOF/GCE. Because functionalized conductive polymers forms on FeCoMOF as a result of presence different metal nodes, electroanalytical performance is greatly enhanced. For the electrochemical detection of Hg+2, the GCE treated with FeCoMOF/PANI-NH2 nanocomposite demonstrated the greatest performance. Furthermore, the findings from the electrochemical impedance spectrum (EIS) and cyclic voltammetry (CV) tests verified that the FeCOMOF/PANI-NH2 increased the rate of electron transfer at the solid-liquid interface.enDepartment of ChemistryChemistrySP22ProfilingNutritional QualityChicken MeatWater-Soluble VitaminsThesis
