Abstract

In this study MAGNETITE nonoparticles were modified with 5-amino-1,3,4-THIADIAZOLE-thiol (AMT) molecules and evaluated as nanoadsorbent for removing NILE BLUE as a dye from aqueous solutions. nanoparticles were characterized by X-Ray, TEM and FT-IR. The dye adsorption was examined by batch equilibrium technique. Also batch studies were performed to find various experimental parameters like pH, contact time and the amount of adsorbent. Equilibrium for adsorption on Fe304-AMT nanoparticles was reached in 30 min. Equilibrium isotherms were analyzed by Freundlich and Langmuir models. Isotherm analyzes showed the experimental adsorption data were well fitted to the Langmuir isotherm model. The Langmuir adsorption capacity was found to be 142,857 mg g-1. The adsorption data were also fitted to kinetic pseudo-first-order and pseudo second-order models. Kinetic studies show that the adsorption followed pseudo-second-order model. The nanoadsorbent can be easily separated from aqueous solution by a magnet. The reform process of magnetic nanosorbent (Fe304-AMT) was performed with ethanol.
