dc.description.abstractIn this study, acid-functionalized multi-walled carbon nanotubes (MWCNTs-COOH) were synthesized by subjecting them to acid treatment and subsequently incorporating magnetite (Fe3O4) nanoparticles onto their surface (MWCNTs-COOH/Fe3O4) through co-precipitating Fe2+ and Fe3+ in the MWCNTs-COOH colloidal suspension. These were then subjected to comprehensive characterization using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller surface area analysis (BET), and Vibrating sample magnetometer (VSM). The adsorption efficiency of the synthesized MWCNTs-COOH/Fe3O4 nanocomposite for the removal of Maxilon Red GRL dye (MR GRL) from aqueous solutions was examined under various conditions, including initial MR GRL concentration (50-250 mg/L), solution pH (2-12), adsorbent dose (0.1-1.0 g/L), and temperature (25-55 degrees C). Results indicated that the MWCNTs-COOH/Fe3O4 nanocomposites displayed strong adsorption capabilities for MR GRL in aqueous solutions, and the adsorption process adhered to the Langmuir isotherm model. Kinetic adsorption data were well-fitted to the pseudo-second-order model. At the natural pH of 5.8 and a temperature of 25 degrees C, the adsorption capacity and removal percentage were determined as 188.68 mg/g and 97%, respectively. The adsorption of MR GRL onto MWCNTs-COOH/Fe3O4 was endothermic and spontaneous, according to thermodynamic characteristics. These findings indicate the potential of the newly synthesized adsorbent in advancing water purification through effective adsorptive separation. [GRAPHICS]
