Graphene and its derivatives, characterized by their ultra-high water flux, unique physicochemical properties, and tunable layered structures, have increasingly emerged as a new generation of membrane materials for wastewater treatment. In this study, a novel membrane material was fabricated via vacuum filtration using BiOCl-doped graphene oxide (GO) modified with diethylenetriamine. This modified GO membrane exhibits excellent wettability, with a water contact angle of 0° in air and an oil contact angle of 144.5° underwater. It demonstrates a separation efficiency of 95.2% for kerosene emulsified oil and 90.2% for crude oil emulsified oil. Additionally, this paper provides a detailed investigation into the mechanism by which the membrane material separates emulsified oils, offering new insights for the treatment of oily wastewaters.
