pH Modulated Green Synthesis of Silver Nanoparticles of Ziziphus Mauritiana for its Anti-Pollutant Activity

Abstract

The environment is getting polluted due to frequent release of waste from the industries. Thus the requirement of renewable sources is required that could help in reduction of various harmful products and act as eco- friendly catalysts. The advancement of nanotechnology can be utilized to enhance water quality. A few techniques that can utilize nanotechnology utilize receptive media for partition and filtration, bioremediation and sterilization. Remediation is the procedure to evacuate, limit or kill the water contaminants that can harm human wellbeing or biological communities. The present work investigates the synthesis of silver nanoparticles (AgNPs) by biological method using Ziziphus mauritiana. Silver nanoparticles were successfully synthesized from Ziziphus mauritiana by green synthesis method at different pH range (pH 3, 5, 7, 9, 11, 13). This synthesis was confirmed by surface plasmon resonance which resulted as with the increase of pH range the size of the nanoparticles decreases. Particle extinction coefficient was monitored by the UV-visible spectroscopy. Morphological studies were done using DLS, Zeta Potential and FTIR. The catalytic activity of AgNPs was monitored by antibacterial activity against E.coli and Bacillus subtilis and other properties of catalytic degradation were confirmed by the adsorption of dyes and reduction of pesticides. Thus catalytic activities concluded that with the increase in the pH range the size of the AgNPs decreases and catalytic activity increases.
