Energy efficient green synthesis method of silver nanoparticles (AgNPs) from

\nBiological processes are used to create AgNPs, which are thought to be economical, energy- efficient, and environmentally benign. One safe way to save energy and stay away from organic solvents is to make AgNPs through green synthesis. AgNPs are receiving a lot of attention in the wastewater management domain. The toxicity of heavy metals poses a significant risk of water contamination. AgNPs are useful substitutes for other methods in the removal of pollutants from wastewater bodies due to their improved adsorption capacities. Environmental removal of heavy metals can be significantly improved due to nanotechnology. Low detection and quantification limits, excellent sensitivity and selectivity are benefits of heavy metal removal from water resources using nanotechnology. Although a lot of study was taken up on release of silver nanoparticles (AgNPs) into wastewater and its probable toxicity to microorganisms, little work is taken up on heavy metals removal process. This investigation focused on the removal of heavy metals by \nH.contortus leaf extract. Using the leaf extract, the removal capacities for Chromium (Cr[VI]), Copper (Cu[II]), Zinc (Zn([II]), Cobalt (Co[II]) and Manganese (Mn[II]) were 88.18%, 26.16%, 26.44%, 26.82% and 46.51% respectively. This demonstrates the stimulatory nature of AgNPs towards the heavy metal removal from wastewaters. \n
