Oil spills are a global concern due to their environmental and economical impact. Various commercial systems have been developed to control these spills, including the use of fibers as sorbents. This research investigates the use of various vegetable fibers, namely mixed leaves residues, mixed sawdust, sisal (Agave sisalana), coir fiber (Cocos nucifera), sponge-gourd (Luffa cylindrica) and silk-floss as sorbent materials of crude oil. Sorption tests with crude oil were conducted in deionized and marine water media, with and without agitation. Water uptake by the fibers was investigated by tests in dry conditions and distillation of the impregnated sorbent. The silk-floss fiber showed a very high degree of hydrophobicity and oil sorption capacity of approximately 85goil/g sorbent (in 24hours). Specific gravity measurements and buoyancy tests were also used to evaluate the suitability of these fibers for the intended application.
由于石油泄漏对环境和经济的影响,它已成为全球关注的问题。人们开发了各种商业系统来控制这些泄漏,包括使用纤维作为吸附剂。本研究调查了各种植物纤维,即混合树叶残渣、混合锯末、剑麻(龙舌兰麻)、椰壳纤维(椰子)、丝瓜(圆筒丝瓜)和木棉作为原油吸附材料的情况。在去离子水和海水介质中,在有搅拌和无搅拌的情况下对原油进行了吸附测试。通过在干燥条件下的测试和对浸渍吸附剂的蒸馏来研究纤维的吸水性。木棉纤维表现出非常高的疏水性,其吸油能力约为85克油/克吸附剂(在24小时内)。还使用了比重测量和浮力测试来评估这些纤维在预期应用中的适用性。
