Abstract
Abstract In an era marked by rapid industrialization and heightened automobile usage, the demand for crude oil has surged, inducing ecological degradation and resource depletion. Effective management of intricate oily wastewater presents a formidable challenge. While diverse methods like gravity separation, centrifugation, and membrane techniques are employed for oil-water separation, gravity separation is the prevailing choice, yet limited to unstable emulsions. These methods often involve toxic substances harmful to marine life. Our research focuses on separating oil microemulsions in aqueous solutions. This study explores the application of superparamagnetic chitosan coagulants, revealing an optimal 10 ml dosage for peak efficiency. Aiming for rapid oil separation, we achieved a breakthrough with just 30 minutes, establishing a new benchmark. Rigorous VSM testing solidified the particles' magnetic capabilities, augmented through size reduction. Notably, at a 15% oil concentration, a remarkable 99.26% efficiency in oil separation was achieved, offering potential in microbiology, medicine, and drug delivery systems.
