Fabrication of Electrochemical Sensors for the Sensing of Hazardous Compounds

Abstract

Environmental pollution is a big threat for the world. There are various inorganic/organic pollutants which derailed out from the different industries and have toxic nature. Many compounds such as toluene, hydrazine, nitrite, hydrogen peroxide, resorcinol, 4-chlorophenol, hydroquinone, catechol, phenol, nitro-phenol, and nitrobenzene are widely used in the industries and these compounds are showed hazardous effects on humans, animals, as well as environments. Some of these compounds even in trace amount may harm the human beings. Therefore, the determinations of such compounds are of great importance. Previously various approaches have been made to detect these organic/inorganic compounds. Various research groups have employed different detection techniques which showed good results. Recently, electrochemical approach attracted much attention of the researchers due to its excellent sensitivity, good detection limit, reproducibility, repeatability, simple fabrication procedure, low cost, and high selectivity. In this chapter, fabrication and advantages of electrochemical sensor for the sensing of different analytes have been discussed. Moreover, the role of newly designed and different electrode modifiers for the fabrication of electrochemical sensors has also been discussed. © Springer Nature Switzerland AG 2021.
