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.

Environmental impacts are increasingly due to the human polluting activities. Therefore, there is a need to develop technologies capable of removing contamination and driving the impacted environment as close as possible to its inherent characteristics. One of the major problems still faced is the spill of oil into water. Therefore, to solve the environmental problem, this work shows the use of magnetically modified geopolymer materials as an oil remover from water with a magnet’s aid. The results obtained were outstanding since the average intrinsic oil removal capability (IORC) was 150 g/g. The presented IORC is the largest found in the materials produced by our research group, constituting an extremely encouraging result, mainly because of the ease of preparing the magnetic geopolymer system. Furthermore, the low cost of production and the material’s capability to be reused as filler of polymer or even cementitious matrices allows us to project that this nanocomposite can be widely used, constituting an economically viable alternative for more efficient environmental recovery processes.
