The synthesis of Ag nanoparticles and loading it on activated carbon as a novel adsorbent for removing methyl orange by using surface response methodology

Abstract

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.

Green synthesis of silver nanoparticles doped activated carbon for Rhodamine B dye adsorption

“…Silver nanoparticles doped activated carbon (Ag NPs/AC) is a functional material with various application mainly in adsorption and antibacterial activity. Previous work proven the effectiveness of Ag NPs/AC in removing dye and water pollutants such as phosphate [10], crystal violet [3,12], malachite green [13,14], methyl orange [15,16] and methylene blue [14,17] with no study in removing RB dye. Silver nanoparticles (Ag NPs) can enhance the active sites of activated carbon (AC) for better adsorption capacity.…”

Using Biebersteinia multifida aqueous extract, and the Photocatalytic Activity of Synthesized Silver Nanoparticles

“…The common methods used to remove industrial dyes are electro-coagulation, carbon sorption, redox treatment, flocculation, UV photo-degradation 18 . Reports have shown that metallic nanoparticles can act as photocatalytic agents [19][20][21] . Therefore, in the study we were investigated photocatalytic activity of synthesized Ag NPs using B. multifida extract on MB dye.…”
