Abstract

This study introduces an innovative approach for enhancing oil-water emulsion separation using a polyethersulfone (PES) membrane embedded with a nanocomposite of graphene oxide (GO) and silver oxide (AgO). The composite membrane, incorporating PES and polyvinyl chloride (PVC), demonstrates improved hydrophilicity, structural integrity and resistance to fouling. Physicochemical characterization confirms successful integration of GO and AgO, leading to increased tensile strength, porosity and hydrophilicity. Filtration tests reveal substantial improvements in separating various oils from contaminated wastewater, with the composite membrane exhibiting superior efficiency and reusability compared to pristine PES membranes. This research contributes to the development of environmentally friendly oil-water separation methods with broad industrial applications.

使用氧化石墨烯-氧化银纳米复合材料嵌入聚醚砜膜，通过协同过滤提高油水乳液分离效果。

本研究介绍了一种利用嵌入氧化石墨烯（GO）和氧化银（AgO）纳米复合材料的聚醚砜（PES）膜提高油水乳液分离效果的创新方法。这种包含聚醚砜（PES）和聚氯乙烯（PVC）的复合膜具有更好的亲水性、结构完整性和抗污能力。理化特性分析证实，GO 和 AgO 的成功结合提高了拉伸强度、孔隙率和亲水性。过滤测试表明，复合膜在分离受污染废水中的各种油类方面有很大改进，与原始聚醚砜膜相比，复合膜具有更高的效率和可重复使用性。这项研究有助于开发具有广泛工业应用前景的环保型油水分离方法。
