Detection of pollutants in water bodies: Electrochemical detection or photo-electrochemical detection?
The massive discharge of pollutants including endocrine-disrupting chemicals (EDCs), heavy metals, pharmaceuticals and personal care products (PPCPs) in water bodies, are endangering the ecological environment and human health, and need to be accurately detected. Both electrochemical and photo-electrochemical detection methods have been widely used for the detection of these pollutants, however, which one is the better for the detection of different environmental pollutants? In this feature article, different electrochemical and photo-electrochemical detection methods were summarized, including the principles, classification, common catalysts, and applications. By summarizing the advantages and disadvantages of different detection methods, this review provides a guide for the other researchers to detect pollutants in water bodies by using electrochemical and photo-electrochemical analysis.
