The Synthesis of Ag Nanoparticles and Loading in on Activated Carbon as A Novel Adsorbent for Removing Methyl Orange by Using Surface Response Methodology

摘要

After synthesizing Ag nanoparticles and loading onto activated carbon (from olive stone), the adsorption of methyl orange (MO) onto the prepared nanoparticles was studied. In this connection, the effect of experimental parameters such as pH range, reagent concentration, contact time, dosage amount of adsorbent and so on, on the adsorption process were studied. The experimental results were analyzed upon various kinetic models such as pseudo first order reaction, pseudo second order reaction, Elovich model, intraparticle diffusion model and various adsorption isotherms such as Langmuir isotherm, Freundlich isotherm and Temkin isotherm.
