What is Synthesis and Characterization of Functionalized Polyacrylonitrile Coated with Iron Oxide Nanoparticles and Its Applicability in Nitrate Removal from Aqueous Solution about?

A novel adsorbent, Polyacrylonitrile (PAN)-oxime-nano-Fe 2 O 3 , was developed to remove nitrates from water. The properties of the adsorbent were characterized by transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. Experiments were carried out to investigate the adsorption kinetics and desorption behaviour of the adsorbent. The Langmuir, Freundlich, and Dubinin-Radushkevich (D-R) isotherms were determined and the results revealed that the adsorption was well explained by the (D-R) model. The experimental data fitted very well the pseudo-second-order kinetic model. Intra-particle diffusion affects nitrate uptake. The experiments showed that the maximum amount of nitrate released after desorption processes was about 50%, indicating that a large portion of nitrate was irreversibly retained by the PAN-oxime-nano-Fe 2 O 3 .
