Oil spills in the marine environment are a rising concern due to their adverse impacts on living creatures and the environment. Hence, remediation methods have been used to remove the oil from the contaminated water. A sorbent material is considered the best method for oil spill absorption. However, commonly used commercial sorbents are made from nonrenewable and nonenvironmentally friendly materials. In this research, natural rubber foam (NRF) was used as a sorbent material with the addition of a filler, i.e., silica and a silica-lignin hybrid, to increase its oil sorption capacity and reusability. The silica and silica-lignin hybrid were extracted from rice husk waste by means of the precipitation method. The silica-lignin hybrid-filled NRF exhibited excellent hydrophobicity, with a water contact angle of 133°, and had more stable reusability compared to unfilled NRF and silica-filled NRF. In addition, the optimum oil absorption capacity of silica-lignin hybrid-filled NRF was 1.36 g g. Overall, the results showed that silica-lignin hybrid-filled NRF has the potential to be developed as a green oil absorbent material and is promising in terms of economic and environmental aspects.
海洋环境中的石油泄漏因其对生物和环境的不利影响而日益受到关注。因此，人们采用了修复方法来去除受污染水中的石油。吸附材料被认为是吸收石油泄漏的最佳方法。然而，常用的商业吸附剂由不可再生且不环保的材料制成。在本研究中，天然橡胶泡沫（NRF）被用作吸附材料，并添加了填料，即二氧化硅和二氧化硅 - 木质素杂化物，以提高其吸油能力和可重复使用性。二氧化硅和二氧化硅 - 木质素杂化物通过沉淀法从稻壳废料中提取。与未填充的NRF和二氧化硅填充的NRF相比，二氧化硅 - 木质素杂化物填充的NRF表现出优异的疏水性，水接触角为133°，并且具有更稳定的可重复使用性。此外，二氧化硅 - 木质素杂化物填充的NRF的最佳吸油能力为1.36 g/g。总体而言，结果表明，二氧化硅 - 木质素杂化物填充的NRF有潜力被开发为绿色吸油材料，在经济和环境方面都很有前景。
