Abstract

This study presents the synthesis and characterization of barium ferrite/graphene oxide (BaFeO/GO) nanocomposites for the adsorption of brilliant green dye (BGD) from aqueous solutions. BaFeO/GO nanocomposites were fabricated via a co-precipitation method with varying GO content (10-30 wt%), and characterized using Fourier Transform Infra rEd (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Field-Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscope (TEM), Brunauer, Emmett, and Teller (BET), and Vibrating Sample Magnetometer (VSM) techniques. The incorporation of GO enhanced the surface area, reduced BaFeO nanoparticle agglomeration, and introduced additional oxygen-containing functional groups, significantly improving the adsorption performance. Batch adsorption experiments were conducted to evaluate the effects of pH, contact time, adsorbent dose, and initial dye concentration. The maximum dye removal efficiency reached 98.9% with the BaFeO/30%GO composite. Kinetic studies showed excellent agreement with the pseudo-second-order model, while adsorption isotherm analysis indicated that the Langmuir model best fit the equilibrium data, suggesting monolayer adsorption. These results demonstrate the potential of BaFeO/GO nanocomposites as efficient, magnetically separable adsorbents for the removal of cationic dyes from wastewater.

In order for Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group to publish and disseminate research articles, we need non-exclusive publishing rights (transfered from author(s) to publisher). This is determined by a publishing agreement between the Author(s) and Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group. This agreement deals with the transfer or license of the right for publishing to Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group, while Authors still retain significant all copy rights to use and share their own published articles. Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in any databases.

As a journal Author, you have all copy rights for a large range of uses of your article, including use by your employing institute or company.
