Emerging Contaminants in Wastewater: Sensor Potential for Monitoring Electroremediation Systems

Conventional chromatography techniques are the classic standard to detect, in environmental matrices, emerging organic molecules that are on the EU watch list to become pollutants. Those methods are known to be highly selective compared to modern alternatives, such as sensors. Nevertheless, sensors have shown advantages in sample manipulation and preparation, accelerating contamination responses in a cost-effective way. Sensors are becoming attractive to the market since they are sustainable and may achieve highly sensitivity for organic molecules. In addition to methods for detecting contaminants, new removal technologies are also in the spotlight. The combination of sensors and removal treatments can provide powerful tools for the future of environmental monitoring and remediation. However, there is a lack of information when a multi-analyte analysis is the ultimate goal. This chapter discusses the drawbacks, challenges, and advantages of coupling electronic tongues with electrokinetic processes to detect emerging organic contaminants in wastewater.
