Abstract

Gold nanoparticles encapsulated alginate microspheres were synthesized and evaluated as a nanoadsorbent for removing Safranin Orange from aqueous solutions. Gold nanoparticles were prepared and characterized by X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and FT-IR. The adsorption of Safranin Orange was examined by batch technique. The effects of pH, initial Safranin Orange concentration, adsorbent dosage and contact time on the efficiency of Safranin Orange removal were studied for the batch method. The equilibrium data analyzed by using Langmuir and Freundlich isotherm models showed better agreement with the latter model. Kinetic studies were conducted and the resulting data were analyzed using first- and second-order equations; pseudo-second-order kinetic equation was found to provide the best correlation. Repeated adsorption and desorption cycles were performed to examine the stability and reusability of the nanoadsorbent. The result of this study proved high stability and reusability of Gold nanoparticles encapsulated alginate microspheres as an adsorbent for Safranin Orange dye.
