Abstract
In this study, new 2-Hydroxy-1-naphthaldehyde linked magnetic Fe3O4/chitosan-polyacrylamide nanoparticles were prepared. The synthesized nanoparticles were characterized by (FT- IR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), vibrating Sample Magnetometry (VSM) and Termogravimetric Analysis (TGA). The 2-Hydroxy-1-naphthaldehyde modified magnetic Fe3O4/chitosan-polyacrylamide nanoparticles were used as an effective adsorbent for removal of Everzol black from aqueous solutions by batch adsorption procedure. The effects of important parameters on the surface absorption process of Everzol black dye, including pH, contact time, adsorbent dosage and initial dye concentration were studied. The Langmuir and Freundlich adsorption models were used to describe adsorption isotherms and constants.
