This study was conducted to determine the potential of chicken feather mat (CFM), a new biosorbent for oil spill cleanup operations. The surface properties of the CFM in motor oil were determined using Inverse-Gas Chromatography Surface Energy Analyzer and compared to those of polypropylene pad (a conventional sorbent) subjected to the same treatment. The surface properties determined were the Brunauer-Emmett-Teller specific surface area (BET-SSA), dispersive and specific (acid-base) surface energies, specific free energies of adsorption and acid-base numbers, and thermodynamic work of cohesion and adhesion. Results showed that the BET-SSA of the CFM in motor oil (13.67 m/g) was higher than that of polypropylene pad in motor oil (8.03 m/g). Additionally, the results of the dispersive and specific (acid-base) surface energies, specific free energies of adsorption and acid-base numbers, and thermodynamic work of cohesion and adhesion show that the CFM is as hydrophobic and oleophilic as the polypropylene pad, suggesting that the CFM is as good as the polypropylene pad in terms of oil sorption. Thus, CFM, an agrowaste, has the potential to be used as a biosorbent for oil spill cleanup operations.

用于溢油清理的鸡毛垫的表面能量和表面化学

本研究旨在确定鸡毛垫（CFM）这种新型生物吸附剂在溢油清理作业中的潜力。使用反气相色谱表面能分析仪测定机油中 CFM 的表面特性，并与经过相同处理的聚丙烯垫（传统吸附剂）的表面特性进行比较。测定的表面性质包括 Brunauer-Emmett-Teller 比表面积 (BET-SSA)、分散和比（酸碱）表面能、吸附比自由能和酸碱值以及内聚力和粘附力的热力学功。结果表明，CFM 在机油中的 BET-SSA (13.67 m/g) 高于聚丙烯垫在机油中的 BET-SSA (8.03 m/g)。此外，分散和比（酸碱）表面能、比吸附自由能和酸碱值以及内聚力和粘附力的热力学功的结果表明，CFM 与聚丙烯垫一样具有疏水性和亲油性，表明就吸油性而言，CFM 与聚丙烯垫一样好。因此，CFM（一种农业废弃物）有潜力用作溢油清理作业的生物吸附剂。
