This review focuses on monitoring selected organic contaminants utilising an electrochemistry technique due to intrinsic benefits such as simplicity, portability, cost, and improved sensitivity. Because the presence of organic pollutants in water causes a variety of health issues such as tumour, headaches, tiredness, and developmental abnormalities, it is critical to explore an effective approach to quantifying these contaminants in various matrices. Although remarkable results have been documented in the use of conventional techniques in the quantification of organic pollutants, owing to high costs, longer pre-concentration steps and analysis times, high power consumption, and the need for sophisticated skilled personnel, their applications for monitoring organic pollutants on-site have been hampered. The electrochemistry approach has emerged to address the difficulties that have hindered the use of traditional approaches for quantifying organic contaminants in water. Thus, the purpose of this review is to examine the concept of employing electrochemistry techniques to determine organic contaminants in various matrixes, and various recommendations for future research have been highlighted.
