Abstract
This study targeted to generating composites comprised of sugarcane bagasse (SCB) and magnetic particles (MPs) under a facile and low-cost approach. Moreover, the adsorption performance of composites, treated SCB, and MPs for crystal violet (CV) was evaluated. Cellulose fibers were firstly isolated from SCB with a two-step process and employed as a matrix material to randomly adhere MPs via an in situ chemical co-precipitation method at room temperature. The properties of the composite were determined through analysis methods such as X-ray diffractometer (XRD), scanning electron microscopy with energy-dispersive X-ray analysis (EDX/SEM), Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), vibrating sample magnetometer (VSM), and Brunauer–Emmett–Teller (BET). Magnetization, surface area, and pore diameter of magnetic fiber composite were 11.1 emu/g, 20 m2/g, and 0.002 cm3/g, respectively. The characteristic peaks of cellulose and MPs were found in XRD results, whereas the Fe content in composite was 27.52%. FTIR spectra also exposed the characteristic functional groups of MPs and treated SCB. Additionally, the CV removal using composites was evaluated with the adsorption efficiency and capacity of 72.09% and 77.22 mg/g, respectively, at pH 7, an adsorbent dose of 2 g/L, a CV concentration of 150 mg/L within 30 min. The adsorption process corresponded to the Sips model and the pseudo-second-order kinetic model. Besides, the mechanism of CV adsorption was primarily characterized by heterogeneous adsorption on the surface and physical sorption. In short, the obtained composite was a promising adsorbent for treating the dye-containing wastewater.
