Abstract

Background and Objective: Arsenic has long been considered as a heavy metal and toxic pollutant due to its potential to harm the human health and the environment. Adsorption is one of the mechanisms for Arsenic removal from wastewater. Therefore, the purpose of this research was to investigate the feasibility of synthesized chitosan-zirconium magnetic nano fiber on Arsenic Adsorption from wastewater and to evaluate its kinetic and isotherm models. Materials and Methods: Synthesis of nanofibers was performed by electrospinning method and the optimal formulation was determined following the experimental design. Then, kinetics and isotherms of Arsenic Adsorption on the as synthesized nanofibers were investigated. The prepared nanofiber was characterized using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopes (FESEM), Infrared Fourier Transform (FT-IR) and Vibrational Sampler Magnetic Meter (VSM). Results: The optimal formulation was obtained: 2. 84% chitosan, 0. 97% nanozirconium and 0. 94% nano-iron. The Adsorption of Arsenic on synthetic fibers was found to follow quasi-first-order kinetics and the Freundlich isotherm. Furthermore, the effect of initial concentrations of Arsenic, contact time, temperature and pH on Arsenic Adsorption were surveyed. The optimal condition for nitrate Arsenic Adsorption was obtained at initial concentration of 70 mg/L, 45 min contact time and at pH 3. Conclusion: According to the results, the synthesized nanofiber displayed a regular network structure with the distribution of the Zr-nanoparticles in its shape. Also, according to the form of magnetometric analysis, it was found that chitosan-nanosirconium magnetic nanofibers are well magnetized and are free magnetic. Finally, it can be concluded that the synthesized nanosorbent has a high potential for Arsenic removal from industrial effluents.
