摘要

膜过滤因其操作简单、能耗低廉而成为处理石油废水的首选方法之一。本文制备了一种基于丝瓜和稻草的可生物降解超疏水膜(LF-RS),并用十二烷基三乙氧基硅烷对其进行改性,以提高其稳定性、形态和性能。该膜的油/水分离效率为 99.06%,平均水通量为 2057.37 Lm-2h-1,拉伸强度为 11.19 MPa。LF-RS 膜的抗拉强度比 PVDF 膜高 322.47%,比市场上销售的硝化纤维膜高 126.58%。通过分子模拟,我们发现改性后水与膜之间的相互作用能降低了 96.3%,这有利于提高接触角和分离性能。这项研究为大规模、经济高效地制造用于去除污染物的环保膜提供了一种选择。

Efficient Separation of Oil/Water by a Biodegradable and Superhydrophobic Composite Based on Loofah and Rice Straw.

Membrane filtration is one of the preferred choices for petroleum wastewater disposal due to its simplicity and low energy consumption. In this paper, a biodegradable superhydrophobic membrane based on loofah and rice straw (LF-RS) was prepared and modified with dodecyltriethoxysilane to improve its stability, morphology, and performance. The membrane showed an efficiency of 99.06% for oil/water separation with an average water flux of 2057.37 Lm-2h-1 and a tensile strength of 11.19 MPa. The tensile strength of the LF-RS membrane was 322.47% higher than that of the PVDF membrane and 126.58% higher than that of the commercially available nitrocellulose membrane. Through molecular simulations, we showed a 96.3% reduction in interaction energy between water and membrane post-modification, which is beneficial for increasing the contact angle and separation performance. This study provides an option for the large-scale, cost-effective fabrication of eco-friendly membranes for pollutant removal.
