The utilization of bismuth as a sensing material for the detection heavy metal ions has gained significant attention due to its exceptional interfacial activity and selective absorption properties. However, it also poses challenges in terms agglomeration inferior electrical conductivity during synthesis process. This paper employed facile situ electrodeposition approach uniformly grow film on conductive carbon cloth, designated Bi/Ag@CC. Bi/Ag@CC electrode exhibited benign electrochemical properties, enabling application detecting Pb2+ tap water lake samples. Furthermore, this work investigated impact parameters, including electrolyte pH, deposition potential pre-enrichment time, performance. results demonstrated sensor’s wide linear range (from 20 400 ppb) limits (0.15 ion detection, along with excellent anti-interference capabilities satisfactory repeatability, an RSD less than 2.31% (n = 6). offers novel strategy positioning bismuth-based composite promising candidate practical applications.

Most heavy metals pose a threat to ecological systems, making it crucial develop an analytical method simultaneously detect multiple metal ions. In this study, novel electrochemical sensor was fabricated based on Cr-doped CoCo2O4@NiO2 hybrid material for the individual and simultaneous selective detection of nanomolar Pb2+ Cu2+. A CoNi bimetallic metal–organic frameworks (MOF) precursor produced using one-step hydration technique, followed by synthesis through calcination. The results N2 adsorption desorption, along with Scanning electron microscope, revealed that composite exhibited significant specific surface area porous structure, thereby notably enhanced its efficacy in preconcentration characterization valence changes transition ions (Co2+/Co3+ Ni2+/Ni3+) could cyclically catalyze ions, remarkably enhancing performance sensor. addition, Cr doping effectively improved conductivity catalytic material. Differential pulse anodic stripping voltammetry employed investigate ability CoCo2O4@NiO2/GCE Cu2+, both individually simultaneously. established sensing approach detected Cu2+ limits 9.6 11.8 nM, respectively. Moreover, also used environmental food samples. proposed analysis has great potential quantitative analyses monitoring safety fields.
