Electrochemical Sensing of Heavy Metal Ions in Water and Food
This community develops electrochemical sensors and electrodes to detect trace concentrations of toxic heavy metal ions in environmental and food samples.
The work centers on designing modified electrodes, often using carbon-based materials like graphene oxide, carbon nanotubes, and glassy carbon, to enable highly sensitive and simultaneous detection of specific contaminants. Key targets include lead, cadmium, mercury, and zinc ions. Methodologies frequently employ stripping voltammetry and anodic stripping techniques to quantify these metals in water samples and food matrices. Recent efforts integrate nanomaterials, metal-organic frameworks, and hybrid composites to enhance sensor performance and selectivity for trace-level analysis in complex environments.
The largest share of the community's output is found in mercury research, accounting for 3.2% of all mercury research tracked, with 4,136 papers in this group. It also represents 1.2% of bismuth research (1,079 papers) and 1.1% of lead research (2,293 papers).
The community comprises 13,867 papers, primarily published in Electroanalysis, Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, and Analytica Chimica Acta.
Recent work continues to focus on novel electrode materials, such as nickel-based metal-organic frameworks and silica-based composites, for the sensitive detection of multiple heavy metal ions in drinking water and food samples.
