The study explores the fabrication of a composite material derived from banana peel biomass and magnesium oxide (MgO) nanoparticles, optimized for MB removal under controlled conditions. The adsorption process was systematically evalu-ated through advanced characterization techniques, including Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) surface area analysis. The optimized conditions, determined using one-factor-at-a-time (OFAT) analysis and further validated through response surface methodology (RSM), revealed an MB removal efficiency of 96.45% under optimal pH, contact time, composite dosage, and initial dye concentration. The adsorption kinetics followed a pseudo-second-order model, with equilibrium data best fitting the Freundlich isotherm, indicating multilayer adsorption and a significant role of electrostatic interactions. This research underscores the potential of agro-waste-derived nanocomposites as cost-effective and sustainable adsorbents for water purification applications. I look forward to sharing these insights with the conference attendees and engaging in discussions on emerging trends in sustainable environmental technologies.
