Three chemical compounds (A1, A2, and A3) with long alkyl chains (C5, C8, and C10) were used in this work to improve the oleophilic and hydrophobic properties of blank flexible polyurethane (FPU) cubes for oil spill clean-up. Water sorption was observed to be reduced by almost 50% when compared to blank FPU, while crude oil sorption of modified FPU cubes was raised by A1 = 37.16, A2 = 42.68, and A3 = 45.94 g/g, as well as diesel fuel sorption by A1 = 36.72, A2 = 39.80, and A3 = 41.68 g/g. In the water-oil system, the sorption capacity of FPU cubes modified with three new oleophilic organic compounds was increased by A1 = 43.47, A2 = 44.49, and A3 = 45.15 g/g for crude oil spills and by A1 = 34.07, A2 = 34.16, and A3 = 36.05 g/g for diesel fuel spills, compared to blank FPU cubes of 27.29 and 22.28. The findings suggest that the modified FPU cubes could be utilized to clean up oil spills successfully. [ABSTRACT FROM AUTHOR] |
