| Abstract |
Discharge of various types of chemicals and oily wastewater from different types of industries has become a serious global health concern nowadays. Additionally, the frequent oil-leakages/spillages during marine transportation or oil production are also a great waste of valuable natural resources. To address these issues, a variety of oil/water separation methods and novel materials have been reported so far. Most of these synthesized materials suffer from low capacities, that resulting in poor separation selectivity and efficiency. Herein, magnetic metal oxide nano sheets (MNS) were synthesized by a simple molten salt method and used them for the selective oil separation from the oil/water mixture. MNS were coated in sponge or Cu-mesh, and applied for the separation of various oils with different viscosity. The MNS-coated sponge showed excellent separation efficiencies (>99%) for the oil products. The calculated fluxes of the oils and chemicals also exhibited higher with respect to other materials proposed for oil separation. This study will open a new avenue for the design and preparation of innovative material for water purification.
Keywords: Nano sheets, metal oxide.
