Analytica—A Journal of Analytical Chemistry and Chemical Analysis, Journal Year: 2024, Volume and Issue: 5(3), P. 358 - 383

Published: Aug. 2, 2024

Heavy metals represent a class of chemical elements that includes metalloids, bases and transition metals, lanthanides, actinides. They are distinguished for their toxicity in small concentrations negative effects on the environment human health; consequently, monitoring has to be improved manage risks. The determination heavy is carried out mainly by analytical methods, using spectroscopy, spectrometry, electroanalysis. However, interest shifted new faster methodologies techniques metal analysis, with particular emphasis voltammetry. Voltammetry preferred detection owing advantages low cost, simplicity, ease operation, fast portability, ability monitor environmental samples field, high sensitivity selectivity. Therefore, this study summarizes applications voltammetry water, soil, plant samples, presents an evaluation sensitivity, selectivity, applicability.
