Ceramic membranes offer significant potential for addressing challenging and harsh wastewater streams such as produced water (PW) and surfactant-stabilized oil/water (O/W) emulsions. This study focuses on developing a stable and a uniformly structured active layer solely composed of MIL-125-NH₂ MOF on a ceramic Alumina support. A stable covalent bonding approach was employed using interfacial polymerization, with isophthaloyl chloride (IPC) acting as the organic crosslinker during interfacial polymerization reaction. Three distinct MIL-125-NH₂ decorated membranes M50, M75, and M100 were prepared by using varying MOF concentrations. Surface wettability analysis of the membranes indicated that the MIL-125-NH₂ MOF active layer displayed super-hydrophilic characteristics in the air (water contact angle = 0°) and super-oleophobic characteristics underwater (oil contact angle = 161.5°). In oil separation experiments, all the MIL-125-NH₂ deposited membranes displayed >99% oil rejection. Among the fabricated membranes, M50 demonstrated the highest water flux of 2100 Lm⁻² h⁻¹ under a transmembrane pressure of 2 bar. The MIL-125-NH₂ MOF deposited membranes also showed stable performance under longer-run filtration. This study would be a simple and effective method of decorating MOFs as an active layer on ceramic support for efficient O/W emulsion separation and desalination applications.

陶瓷膜在解决具有挑战性和恶劣性的废水流（例如采出水（PW）和表面活性剂稳定的油/水（O/W）乳液）方面具有巨大的潜力。本研究的重点是在陶瓷氧化铝载体上开发仅由 MIL-125-NH ₂ MOF组成的稳定且结构均匀的活性层。使用界面聚合采用稳定的共价键合方法，在界面聚合反应过程中间苯二甲酰氯（IPC）充当有机交联剂。使用不同的MOF浓度制备了三种不同的MIL-125-NH ₂装饰膜M50、M75和M100。膜的表面润湿性分析表明，MIL-125-NH ₂ MOF活性层在空气中表现出超亲水特性（水接触角=0°），在水下表现出超疏油特性（油接触角=161.5°）。在油分离实验中，所有MIL-125-NH ₂沉积膜均表现出>99%的油截留率。在所制造的膜中，M50在2巴的跨膜压力下表现出最高的水通量2100 Lm ^-2  h ^-1 。 MIL-125-NH ₂ MOF 沉积膜在长期过滤下也表现出稳定的性能。这项研究将是一种简单而有效的方法，将 MOF 装饰为陶瓷载体上的活性层，以实现高效的 O/W 乳液分离和海水淡化应用。
