Treatment of Water Effluents Using Silver Nanoparticles

Abstract

The water from industries with potential hazardous organic matters when discharged into the water bodies cause undesirable effects to the environment, aquatic life and human health. So it is necessary to treat waste water prior to their disposal. Degradation of organic pollutants is a major concern in the present scenario due to its stability, fastness to sunlight, resistance to degrading agents or microbial attack. It is mainly achieved by silver metal nanoparticles synthesised by green route. Degradation of dyes using metal nanoparticles is an environmental benign method. Silver metal nanoparticles show high catalytic potential due to its unique property of smaller structure and large surface to volume ratio. This review provides a detailed report of the degradation of various organic pollutants by phyto synthesised silver metal nanoparticles.

Comparative Study of Green Synthesized Silver (Ag) Nanoparticles for Wastewater Treatment Over Filtration Technique for Bioremediation Application

“…According to Prasad et al nanoparticles operate as nanosorbents for the removal of heavy metals and organic contaminants, and when doped with additional metals, their activity increases significantly (Prasad et al 2019). Beena Mathew et al concluded that thephotocatalytic activity of silver nanoparticles improves the efficiency of dye removal in wastewater (Mathew 2018). Silver nanoparticles developed by Mohammed TahaMoustafa et al exhibit strong antibacterial action against both gramme positive and gramme negative microorganisms (Moustafa 2017).…”
