The possibility of using a ferrofluid synthesized from industrial iron-containing waste for the purification of water from oil products has been investigated. Fourier-transform infrared spectroscopy confirmed that the composition and properties of the obtained magnetic fluid are comparable to a sample synthesized from pure reagents. It has been shown that purification using a magnetic fluid setup allows for a significant reduction in the concentration of oil products. To assess the effectiveness of the method, bioassays of the treated water were conducted on crustaceans and algae. It was established that the technology ensures a substantial reduction in acute toxicity; however, residual toxicity indicates the need for further process optimization.The aim of this study is to conduct a comprehensive assessment of the effectiveness of the technology for the volumetric purification of water contaminated with oil products using ferrofluid, through biological (bioassay) methods of analysis.The objects of the study are industrial iron-containing waste, kerosene-based ferrofluid, and wastewater.
