Abstract


This article describes a novel and efficient MCTS/GO nanocomposite for the accumulation and removal of a hazardous azo dye (Chrysoidine Y) from its aqueous solutions. Magnetic Chitosan /graphene oxide (MCTS/GO) nanocomposite adsorbent was prepared by wet-spinning technique, was used as accumulation and removal of Chrysoidine Y from aqueous solution. The structure and morphology of MCTS/GO nanocomposites were inves- tigated using transmission electron microscope (TEM) and Fourier transform infrared (FTIR) spectroscopy were carried out on the MCTS/GO before the Chrysoidine Y (CY) accumulation experiments. The adsorption kinetics and isotherm studies were conducted under different conditions (pH = 3-7 and CY concentration = 100-400 mg/L) to examine the accumultion efficiency of the MCTS/GO towards CY in aqueous solution. The kinetics data of the adsorption process were analyzed using different kinetic models in order to investigate the adsorption behavior of CY on MCTS/GO. The results showed that the maximum adsorption capacity of the MCTS/GO nanocomposites towards CY can achieve up to ~700 mg/g for the adsorption at 300 mg/L CY. Kinetic data of adsorption process were found to fit pseudo-second order model as compared with pseudo-first-order model. The intraparticle dif- fusion model suggested that the adsorption process of MCTS/GO towards CY was dominated by the external mass transfer of CY molecules to the surface of MCTS/GO.
