Electrochemical and Spectrometric Detection of Heavy Metals and Platinum Group Elements
This research community develops methods to identify and quantify trace levels of toxic heavy metals and valuable platinum group elements in water, food, and environmental samples.
The work centers on two primary analytical approaches: electrochemical sensing and optical spectrometry. Electrochemical methods frequently employ modified electrodes, including carbon paste, glassy carbon, and graphene oxide, often enhanced with nanomaterials or metal-organic frameworks to improve sensitivity for ions like lead, cadmium, and mercury. Spectrometric techniques rely heavily on inductively coupled plasma mass spectrometry and atomic absorption to determine trace concentrations. A significant portion of the literature focuses on the simultaneous determination of multiple metal ions in complex matrices, with specific attention to water samples, food safety, and the recovery of palladium and platinum from wastewater.
The community is most prominent in research concerning mercury, where it accounts for 3.8% of all mercury studies, and platinum, representing 2.6% of platinum research. It also holds a 2.1% share of lead and cadmium research, with 4,498 papers on lead and 3,368 on cadmium within this group.
The community comprises 60,576 papers, primarily published in Analytica Chimica Acta, Analytical Chemistry, and Talanta.
Recent work continues to focus on developing highly sensitive electrochemical sensors using advanced materials like covalent organic frameworks and metal-organic frameworks for the simultaneous detection of multiple heavy metal ions in drinking water and food samples.
