Optical Sensing of Copper and Its Removal by Different Environmental Technologies

Abstract

Heavy metal detection by sensing technology is an important field of research as the heavy metals are toxic and are found in the environmental matrix. The detailed structure and sensing property studies of the probes enhance the knowledge for the future design and development of a probe for same metal. In this review, we have discussed about different chemo and fluorosensors for copper detection and their sensing parameters in different media with detailed structural studies. The removal of copper from the water medium is also addressed in this review. Application of membrane process, adsorption, and electrocoagulation along with their implementation challenges are discussed.
