Many oil adsorption materials are composed of nonrenewable raw materials, and their disposal can increase resource consumption and cause new environmental pollution. In this paper, the carbonized (CEC) were immobilized with FeO magnetic nanoparticles and modified with 1, 1, 2, 2-perfluorooctyltriethoxysilane (PFOS) to prepare an oil adsorption material, referred to here as CEC/FeO/PFOS. The magnetic and mechanical strength of the CEC was enhanced by adding FeO magnetic particles, which enable it efficient to dispose the oil/water solution. CEC/FeO/PFOS shows high porosity (83.53%), low skeletal density (0.487 g/cm), excellent magnetism, ultrahigh oil absorption capacity (49.94-140.90 g/g), hydrophobic performances with a water contact angle of 150.1 ± 2.3°, and a sliding angle of 10.5°. It is worth noting that the material can be recycled, and the absorbed oil is obtained by distillation. Therefore, this work may provide a candidate for solving the problem of oil pollution using .
许多吸油材料由不可再生原料组成,其处理会增加资源消耗并造成新的环境污染。本文将碳化纤维素(CEC)用FeO磁性纳米颗粒固定,并以1,1,2,2-全氟辛基三乙氧基硅烷(PFOS)改性,制备了一种吸油材料,在此称为CEC/FeO/PFOS。通过添加FeO磁性颗粒增强了CEC的磁性和机械强度,使其能够高效处理油/水溶液。CEC/FeO/PFOS具有高孔隙率(83.53%)、低骨架密度(0.487 g/cm)、优异的磁性、超高吸油能力(49.94 - 140.90 g/g)、疏水性能,水接触角为150.1±2.3°,滑动角为10.5°。值得注意的是,该材料可回收利用,吸附的油通过蒸馏获得。因此,这项工作可能为解决油污问题提供一种候选方案。
