Colorimetric Detection of Mercury Using Silver Nanoparticles: A Review

Manufacturing nanometals that use natural materials as bioreductant media is still a significant concern due to their environmentally friendly properties. The use of silver nanoparticles prepared using plants or organic materials. They are used for the rapid detection of sustainable mercury ions. The use of these natural materials is capable of producing stable nanoparticles and environmentally friendly nanoparticle synthesis. In this paper, we will report the synthesis of silver nanoparticles with various types of reducers and stabilizers, mechanisms, and nanoparticle characterization for applications of colorimetric sensors of mercury ions in water pollutants. The aim is for the reader to obtain comprehensive information about the ability of the silver nanoparticle as a colorimeter sensor.
