Abstract
This study investigates the efficacy of sugarcane bagasse pulp (SCBP) as a sustainable adsorbent for the removal of Methylene Blue (MB) dye from aqueous solutions. Comprehensive analyses employing Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) confirmed the SCBP’s potential for both physical and chemical adsorption. Experimental parameters such as temperature, adsorbent dose, contact time, initial dye concentration, pH, particle size, and shaking speed were systematically varied to optimize the adsorption process. The results indicated that removal efficiency improved with increasing temperature, peaking at 40°C, and was favored under alkaline conditions. The adsorbent dose was found to be most effective at 20 g/L, while the optimal contact time and initial dye concentration were determined to be 15 minutes and 25 mg/L, respectively. Shaking speed and particle size also influenced the adsorption efficiency, with 130 rpm and 500 μm identified as the respective optimal values. An artificial neural network (ANN) model was employed to predict the adsorption efficiency, yielding an R2 of 0.98158, which underscores the model’s reliability. The ANN model identified the best removal efficiency under specific conditions, achieving a 95% removal rate. Furthermore, the study explored the use of SCBP for the preparation of activated carbon (AC) and the fabrication of adsorptive membranes. The physically prepared AC demonstrated a high removal efficiency of 98.29% ± 0.68% under optimum conditions. The adsorptive membranes, fabricated using surface coating and mixing methods, were characterized by FTIR and SEM, revealing their affinity for MB dye. The mixed membrane exhibited superior performance, achieving a removal efficiency of 99.4% after 240 minutes. The findings suggest that SCBP is an effective and sustainable adsorbent for dye removal, with potential applications in regions with abundant sugarcane bagasse. The study highlights the promising use of SCBP in wastewater treatment, contributing to the objectives of sustainable development and offering insights for future research.
