Protecting the environment is important for its impact on the life of humans and organisms. Oil pollution is one of the most important factors affecting the life of creatures. Here we are looking for the way to magnetize oil contamination by modified sawdust. The iron oxide nanoparticles were coated in situ on the sawdust using co-precipitation method, which magnetized the sawdust. Subsequently, the magnetic sawdust was successfully functionalized with a saline coupling agent to form a highly hydrophobic and oleophilic surface. FE-SEM, FTIR, EDXA, VSM, WCA and optical microscopy were performed to complete characterization of the products. In addition, a new magnetorheological (MR) fluid based on the crude oil and magnetized sawdust was developed and its rheological properties studied by a rheometer furnished with a magnetic field generator. The results were completely fitted using Bingham model. The strong MR response induced in the crude oil by adding the modified sawdust could exhibit a high crude oil removal capacity of about 47 times the modified sawdust weight.

保护环境对于环境对人类和生物的生命至关重要。石油污染是影响生物生命的最重要因素之一。在这里，我们正在寻找通过改性木屑来磁化油污的方法。使用共沉淀法将氧化铁纳米颗粒原位涂覆在木屑上，使木屑磁化。随后，用盐偶联剂成功地将磁性木屑功能化，以形成高度疏水和亲油的表面。进行了FE-SEM，FTIR，EDXA，VSM，WCA和光学显微镜检查，以完成产品的表征。此外，还开发了一种基于原油和磁化木屑的新型磁流变（MR）流体，并通过配备磁场发生器的流变仪研究了其流变特性。使用Bingham模型对结果进行完全拟合。通过添加改性木屑在原油中诱导的强MR响应可表现出高原油去除能力，约为改性木屑重量的47倍。
