| Abstract | The present study reports using waste silk fabric functionalized using Polylactic acid (PLA) and Activated charcoal for oil/solvent recovery from simulated seawater (3.5% NaCl-based water). An average of 91% separation was visible in the functionalized waste silk fabric with an efficiency up to 20 cycles towards petroleum oils/solvents from simulated seawater. Further, the functionalized waste fabric showed hydrophobic properties with a water-based contact angle of 105 degrees and oil/solvent absorption towards petroleum oils and organic solvent, with a surface free energy of 52.46 mN m-1. The functionalized waste silk also showed permeation flux of 658, 386, and 993 L m- 2 h-1, for Petrol, Diesel, and n-Hexane, respectively. The results show that PLA/Activatedcharcoal engineered waste silk can be effectively applied for practical oil/solvent recovery from simulated seawater. Utilizing waste silk fabric further supports in reducing the global carbon footprints as silk does not emit and/-or produce carbon dioxide due to its green origin and generating the circular economy approach. |
