abstract
Chemical analytical methods play a fundamental role in process and waste control in industry, and both classical and instrumental are known in this sector. Optical and chromatographic methods have been more widely used within the industrial sector than electroanalytical methods. Research into increasingly modern electrochemical sensors, many of which are based on advanced materials, led to achieving very low detection limits with extensive linear ranges and good accuracy. In addition, electroanalysis using sensors is becoming increasingly automated, eliminating the need for the highly specialized knowledge previously required for this type of procedure. The application of electrochemical sensors in industry brings important operational and economic advantages, such as reducing analysis time, eliminating sample preparation steps, processing a larger number of samples per day, etc. This paper reviews recent advances (2019 – 2024) in electrochemical sensors applied to samples relevant to various industries, including wastewater and the natural waters into which they are discharged. A comparative discussion on electrochemical sensors for pharmaceutical, food, mining, and petrochemical industries was performed.
