Synthesis of Plant-Mediated Metallic Nanoparticles for Wastewater Treatment

Nanotechnology is broadly used in the different fields of science such as biomedicine, pharmaceuticals, electronics, diagnostic instruments, and environmental detection. Nanoparticles have great potential to purify wastewater and decontaminate wastewater. Nanoparticles can eliminate inorganic/organic pollutants, heavy metals, and chemical dye from contaminated water. Nanoparticles are synthesized with various methods such as physical, chemical, and biosynthesized. Plant extract is used for the synthesis of metallic nanoparticles because plant extract contains different types of primary and secondary metabolites. These metabolites act as stabilizing and reducing agents in the synthesis of novel metallic nanoparticles. The size and shape of nanoparticles have unique properties; thus, they are widely used for removing pollutants from water. The chapter discussed green synthesized metallic nanoparticles and their application in the treatment of wastewater.
