The petroleum sorption capacities of plant fibers from Eucalyptus sp., Bambusa tuldoides, and sugarcane bagasse fibers were investigated as innovative and low-cost alternatives from renewable sources. Characterization of the fibers was performed according to their morphological aspects and physicochemical characteristics. The oil used was classified according to its American Petroleum Institute (API) gravity, viscosity, and density. Sorption tests performed with crude oil mixed with deionized water in a static or agitated system revealed maximum sorption capacities of the fibers in the range of 5.08–5.87 g g⁻¹. The biosorbent based on eucalyptus fibers is a promising material for the cleaning of oil spills in water bodies as it is the most hydrophobic material. Sugarcane bagasse and bamboo gave good results for oil sorption applications in the absence of water, validating their use as well.

不同植物纤维作为天然吸附剂的应用及其在原油水净化中的应用

来自桉树、竹和甘蔗渣纤维的植物纤维的石油吸附能力被研究为可再生资源的创新和低成本替代品。纤维的表征是根据它们的形态学方面和物理化学特征进行的。使用的油根据其美国石油协会 (API) 的重力、粘度和密度进行分类。在静态或搅拌系统中用原油与去离子水混合进行的吸附测试表明，纤维的最大吸附能力在 5.08–5.87 g g ^-1范围内. 基于桉树纤维的生物吸附剂是一种很有前途的材料，用于清洁水体中的溢油，因为它是最疏水的材料。甘蔗渣和竹子在缺水的情况下为吸油应用提供了良好的结果，也验证了它们的用途。
