Electrochemical Sensors for Heavy Metal Ion Detection in Water and Food
This community develops electrochemical sensors and electrodes to detect and quantify toxic heavy metal ions, primarily cadmium, lead, and mercury, in water and food samples.
The work centers on designing modified electrodes using materials such as bismuth films, graphene oxide, carbon nanotubes, and metal-organic frameworks to enhance sensitivity. The primary analytical technique is stripping voltammetry, often anodic stripping, which allows for the simultaneous detection of multiple metal ions in a single sample. Applications are heavily focused on environmental monitoring of water sources and food safety testing, with a strong emphasis on achieving trace-level detection limits. The research consistently aims to improve the selectivity and speed of these sensors for practical use in complex matrices like drinking water, environmental samples, and various food products.
The largest share of the community's output is found in bismuth research, accounting for 3.2% of all bismuth research, and 1,037 papers here. Mercury research also features prominently, with 444 papers representing 1.3% of that element's tracked literature.
The community comprises 3,747 papers, publishing most frequently in Electroanalysis, the Journal of Electroanalytical Chemistry, and Electrochimica Acta.
Recent work continues to focus on novel nanocomposite materials, such as metal-organic framework hybrids and silica-based electrodes, to improve the simultaneous detection of ultra-trace heavy metals in drinking water and food samples.
