π§ͺ Magnetic tech cleans oil from water fast
Researchers investigated oil-in-water emulsion demulsification using magnetic nanoparticles (MNP@SDBS) via magnetophoresis. The study, conducted by various institutions, tested materials from commercial salts and Fe-rich sands on August 31, 2026. Both SMNP@SDBS and NMNP@SDBS achieved 98% hydrocarbon removal in just 1 minute at 2500 ppm. These findings confirm that sand-derived magnetic demulsifiers perform comparably to salt-synthesized ones. Future work will focus on optimizing the use and recovery of these reusable materials. π§ͺ
