The increasing rate of oil and gas production has contributed to a release of oil/water emulsion or mixtures to the environment, becoming a pressing issue. At the same time, pollution of the toxic cigarette butt has also become a growing concern. This study explored utilization of cigarette butt waste as a source of cellulose acetate-based (CA) polymer to develop a phase inverted membrane for treatment of oil/water emulsion and compare it with commercial polyvinylidene difluoride (PVDF) and polysulfone (PSF). Results show that the CA-based membrane from waste cigarette butt offers an eco-friendly material without compromising the separation efficiency, with a pore size range suitable for oil/water emulsion filtration with the rejection of >94.0%. The CA membrane poses good structural property similar to the established PVDF and PSF membranes with equally asymmetric morphology. It also poses hydrophilicity properties with a contact angle of 74.5°, lower than both PVDF and PSF membranes. The pore size of CA demonstrates that the CA is within the microfiltration range with a mean flow pore size of 0.17 µm. The developed CA membrane shows a promising oil/water emulsion permeability of 180 L m h bar after five filtration cycles. However, it still suffers a high degree of irreversible fouling (>90.0%), suggesting potential future improvements in terms of membrane fouling management. Overall, this study demonstrates a sustainable approach to addressing oil/water emulsion pollution treated CA membrane from cigarette butt waste.
石油和天然气产量的不断增加导致油/水乳液或混合物排放到环境中，这已成为一个紧迫的问题。与此同时，有毒烟头的污染也日益受到关注。本研究探索了将废弃烟头作为醋酸纤维素基（CA）聚合物的来源，以开发一种用于处理油/水乳液的相转化膜，并将其与商用聚偏二氟乙烯（PVDF）和聚砜（PSF）进行比较。结果表明，由废弃烟头制成的CA基膜提供了一种环保材料，且不影响分离效率，其孔径范围适合油/水乳液过滤，截留率>94.0%。CA膜具有与已有的PVDF和PSF膜相似的良好结构性能，形态同样不对称。它还具有亲水性，接触角为74.5°，低于PVDF和PSF膜。CA的孔径表明其处于微滤范围内，平均流动孔径为0.17µm。经过五个过滤循环后，所开发的CA膜显示出有前景的油/水乳液渗透率，为180 L m h bar。然而，它仍然遭受高度的不可逆污染（>90.0%），这表明在膜污染管理方面未来有潜在的改进空间。总体而言，本研究展示了一种可持续的方法来解决油/水乳液污染问题，即利用废弃烟头制备CA膜进行处理。
