A highly sensitive electrochemical sensor for the detection of lead(ii) ions utilizing rice-shaped bimetallic MOFs incorporated reduced graphene oxide.

ABSTRACT: The detection of lead ions (Pb²⁺) in water is of critical importance due to the harmful effects of lead on human health and the environment. Traditional detection methods often require high user expertise, expensive equipment, and complex analytical procedures. Electrochemical sensors have emerged as effective alternatives due to their portability and affordability. In this study, a novel electrochemical sensor was developed for the sensitive and selective detection of Pb²⁺ based on glassy carbon electrodes (GCE) modified with bimetallic metal-organic frameworks (MOFs) and reduced graphene oxide (rGO). The bimetallic MOFs were successfully synthesized via a hydrothermal method, combining two metal centers Fe and Mg linked to a 1,4-benzene dicarboxylate ligand (
