Hydrophobic modified PET ion track-etched membrane for oil/water separation
Journal of Water Process Engineering(2023)
摘要
Due to the increase in oil spills and the high organic contamination of the marine environment, it is necessary to develop an oil/water separation technology with low cost and high efficiency. Membrane separation technology has been proven to be an important technology used in the oil/water separation area. Herein, PET ion track-etched membranes with channel sizes of 310 nm, 650 nm, 1050 nm, and 1950 nm were hydrophobically modified by chemical grafting using propyltrichlorosilane and o-xylene as modifier and solvent, respectively. The modified PET ion track-etched membranes were found to exhibit a maximum water contact angle of 140.81° and possessed excellent hydrophobic property with modifying conditions of 80 mM modifier and 24 h modification time. It demonstrated the grafted propyl groups on the PET ion track-etched membrane played a key role in the increase of hydrophobic property. After modification, the PET ion track etched membrane had a high oil/water separation ratio of 99.87% and a flux of 12,158.24 L/m2·h with good running stability. This work provided a cost-effective and facile approach to distinctly improve the ion track-etched membrane performance on durable oil/water separation.
