Highly hydrophobic oil−water separation membrane: reutilization of waste reverse osmosis membrane

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1606-1615 doi: 10.1007/s11705-022-2200-0

Abstract: In this work, the base nonwoven layer of the wasted reverse osmosis membrane was successfully modifiedinto the hydrophobic membrane via surface deposition strategy including TiO2 and 1H,1H,2HThe optimally modified membrane displayed good hydrophobicity with a contact angle of 135.2° ± 0.3°,This work might provide a new avenue for recycling the wasted reverse osmosis membrane used in oily wastewater
