Environmental remediation and monitoring of cadmium

摘要: Abstract The complete remediation of extremely toxic elements, such as cadmium, must be achieved to control the various stages in their life cycles, from mining virgin ore using them consumer and industrial end products, recycling. Considerable progress has been made monitoring cadmium ions, but sensors or captors that can simultaneously detect remove metal ions across a wide range environments are still greatly needed. This article reviews tools strategies for environmental with special emphasis on state-of-the-art colorimetric sensors. Selective based immobilization hydrophobic hydrophilic chromophore molecules into nanosized space cavities have significant advantages because dual functionality, namely, early warning “detection” removal ions. review concludes thorough evaluation emerging challenges future requirements monitoring, detecting, removing matrices.
