Abstract:
: The aim/objectives of study is to investigates the properties of untreated and treated coconut husk fibers, focusing on the structural and chemical changes that occur during various treatment processes. Ionic liquids (ILs), unique salts composed of organic cations and inorganic or organic anions, remain in liquid form at room temperature. The research methodology of study is characterized by low vapor pressure, excellent thermal stability, and high solubility, making them highly versatile for a wide range of applications, particularly in biomass processing. Coconut husk fibers, known for their strength, durability, and natural resistance to wear, hold significant potential for applications in composites and environmental solutions. The theoretical and practical implications: To assess the effects of different treatments on the fibers' morphology, elemental, and chemical composition, this research employs methods such as Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and Carbon, Hydrogen, Nitrogen, Sulfur (CHNS) elemental analysis. The data analysis and research findings: The findings reveal that treatments using Triethylammonium Sulfate (TEAS) and Diethylammonium Sulfate (DEAS) yield 75.33% and 83.66%, respectively, under optimal conditions of 130°C for 5 hours. The contributions of study that these results suggest that these ILs effectively facilitate lignocellulose breakdown in coconut husk fibers, offering valuable insights into the structural changes induced by the treatments.
