With the increase in production of oily wastewaters and the strict regulations on its discharge, the development of materials and methods for oil/water separation is very critical to modern society. There are various types of oil/water separation environments. Among them, tricky situations that restrict man access have hindered efficient oil/water separation processes. Selective absorption of water or oil by hydrophilic or hydrophobic absorbent, respectively, is useful for industrial processes that use two, more, or mixed solvents. Moreover, hydrophilic or hydrophobic absorbent with a magnetic property has advantages over general absorbents if it is used in appropriate application fields. Herein, we report that hydrophilic or hydrophobic porous magnetic absorbents that possess enough magnetic force to be manipulated by an external magnetic field for tricky oil/water separation. |
