Abstract
This study synthesized a cellulose-based aerogel from bagasse with activated carbon and tested its effectiveness for crude oil spill remediation. Scanning electron microscopy (SEM) analyzed the morphology of bagasse fibers and their integration within the aerogel. Brunauer-Emmett-Teller (BET) analysis revealed a surface area of 34.53 m²/g, a micropore volume of 0.040 cm³/g, and 96.4% porosity. The Barrett-Joyner-Halenda (BJH) plot showed predominantly mesoporous features with an average pore diameter of 28.2 Å. X-ray diffraction (XRD) indicated a crystalline structure with a 76.4% crystallinity index. Fourier-transform infrared (FTIR) spectroscopy confirmed the presence of functional groups. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) showed excellent thermal stability. The aerogel exhibited an oil adsorption capacity of 12.78 grams per gram in seawater, demonstrating its effectiveness in oil spill cleanup.
