Research on the construction of portable electrochemical sensors for environmental compounds quality monitoring

Abstract

The environment is important for human survival, but because of everyday human activities, many pollutants in the drinking water, food and environment may increasingly contribute to the problem of environmental contamination and pose a significant threat to human health. Therefore, the fast and effective monitoring of environmental compound concentrations in environmental samples is required. Electrochemical sensors offer huge potential for online monitoring of specific pollutants in complex environments, owing to their high sensitivity, good selectivity, low cost, simple operation, and high accuracy. This has made them a hot topic. Furthermore, with development of portable electronic technology, the portable electrochemical sensing system with miniaturization has booming in many fields. Therefore, this paper systematically reviews a variety of portable electrochemical sensors that are used for the analysis of pollutants in the environment, and summarizes the current research direction. This is expected to provide researchers with new research ideas and perspectives.
