Abstract:
Heavy metals contamination is a severe quality concern in many fast-growing cities, because maintenance
of water quality and sanitation infrastructure were not increased with population and urbanization growth
especially for the developing countries. Lead (Pb²⁺) and Mercury (Hg²⁺), in water pose enormous
environmental and health issues that make it imperative to produce an efficient detection method. SU-101
MOF@Ppy NWs is a conducting nanocomposite material composed of Bismuth metal with ellagic acid
as a linker, fabricated with the help of the novel microwave-assisted methodology, in this research study.
Before testing the conductivity of this nanocomposite, FTIR analysis was done appropriately to ensure
the structural reliability and purity of the obtained compounds. Electrochemical studies, including CV and
EIS, demonstrated enhanced conductivity of the SU-101 MOF@PpyNWs nanocomposite. Square Wave
Voltammetry further proved it to be a promising detection material for Lead and Mercury, suggesting its
importance as a heavy metal ion detector in aqueous media. The Limit of Detection calculated was
2.026ng/L and 2.184ng/L for Pb2+ and Hg2+ respectively.
