Production of Ni0.5Co0.5Fe2O4/Activated Carbon@Chitosan Magnetic Nanobiocomposite as a Novel Adsorbent of Methylene Blue in Aqueous Solutions

Dyes are carcinogenic and mutagenic molecules that are used in various industries. Disposal of dyes into water sources can lead to the death of organisms. Methylene blue is a cationic toxic dye due to the presence of aromatic rings in its structure and cannot be degraded through natural methods. Therefore, chemical, physical, and biological water treatment methods have been proposed for the elimination of toxic dyes. Adsorption is one of the most appropriate methods in this regard because of its cost-effectiveness and high efficiency. In this study, we synthesized a magnetic nanobiocomposite of ferrite nickel-cobalt/activated carbon@chitosan as an adsorbent. VSM, BET, FESEM, XRD, and FT-IR analyses were performed to evaluate the properties of this nanomaterial including crystallinity, nanostructure, reactions correctness, and magnetism of the compound. We tested the adsorption of methylene blue by the nanobiocomposite through UV-Vis. The results of the analyses and the adsorption test were used to evaluate the efficiency of nanocompound adsorption. This study can pave the way for a wide range of other projects such as changes in reactants and their ratio or change in reaction conditions.
