The interest in magnetic nanoparticles has been growing in recent years, several fields of research are exploring the properties of these materials. Among them, the authors can mention the inclusion of these nanoparticles in materials that perform the cleaning of oil spills, thus producing easy contaminant removal from the place by the aid of the action of a magnetic field. Several materials can be used aiming to this purpose. However, to the best of our knowledge, alkyd resins filled with lignin has never been used as oil spill cleanup tools. So, these materials are prepared and tested using several techniques, such as FTIR, SEM, and XRD. Besides that, the oil spill cleanup capability of the prepared materials is also tested. According to the exponential model used to describe the oil spill cleanup experiments, the best material is able to remove (25 ± 2) g of petroleum from the water. Thus, the presented material can be used as an oil spill cleanup tool, reducing environmental impacts. [ABSTRACT FROM AUTHOR] |
