Microwave-Mediated Green Synthesis of Silver Nanoparticles Using Ficus Elastica Leaf Extract and Application in Air Pollution Controlling Studies

摘要

Silver Nanoparticles are applied in various fields due to its anti bacterial properties. A conventional method for synthesis of AgNP requires dangerous chemical and large amount of energy is released in the process. Environmental friendly techniques are adopted for the synthesis of nanoparticles of silver. The present research work summarizes the green synthesis of silver nanoparticles by using leaf extract of Ficus Elastica and alternative energy sources micro wave irradiation. The synthesized Nanoparticles are characterized by uv - visible spectroscopy and by SEM. The synthesized nanoparticles are applied for controlling SO2and NO2from aqueous solution of SO2and NO2. Batch adsorption studies are carried out. The effect of the temperature on adsorption of aqueous solution is studied at different temperature. A co mparison of kinetic models applied to the adsorption of on silver Nanoparticles was evaluated for the pseudo first order, pseudo second order, Elovich and intraparticle diffusion models respectively. Results show that pseudo second order model was found to correlate the experimental data. Data fitted perfectly into and Freundlich adsorption isotherms
