Graphical Abstract


Carbon electrode materials have generated considerable research interest in recent years due to their ease of use, higher charge transfer kinetics, and cost-effectiveness. Malachite green (MG) is an organic compound with metallic-looking powdered green crystals, which got its name from the color of malachite. MG can be easily converted to leuco-malachite green, a colorless form (LMG). Because both MG forms are dangerous for human health, detecting them in the environment is important. Many researchers across the globe worked on MG detection using various techniques, and this article provides brief information on their results. In this review article, some specific information about electrochemical detection techniques, which are frequently employed for MG determination, is discussed. This review highlights some advances in voltammetric methods using carbon-based electrodes such as glassy carbon, carbon paste, pencil graphite, and their chemically modified forms in various configurations that can be used for the electrochemical detection of MG. Some of the future scopes in using these advanced, carbon-based electrodes in MG determination are also discussed.
