Abstract

This study aimed to synthesize graphene oxide (GO) nanoparticles and subsequently modify them with trimethylsilyl chloride (TMSCl). The modified GO was employed in the fabrication of a polysulfone-graphene oxide (PSf-GO) ultrafiltration mixed-matrix membrane for oil and water separation. PSf-GO ultrafiltration mixed-matrix membranes were fabricated using different amounts of modified GO. The structure, properties, and characteristics of the synthesized GO and fabricated membranes were studied using various techniques, including contact angle measurements, atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The performance of the membranes in the separation of oil and water and their antifouling affinities were evaluated and compared. Contact angle measurements indicated that the addition of GO nanoparticles increased the hydrophilicity of the membranes. The UF-0.50 (0.50%Wt GO@TMSCl) membrane demonstrated a water flux of 113.35 L/m² h and oil rejection of 97.44% during the ultrafiltration process, representing the highest performance among the fabricated membranes. Membrane fouling analysis revealed that this membrane performed better than the others, which could be attributed to the proper and uniform nanoparticle loading. The most favorable UF membrane antifouling performance was observed for the UF-0.5 membrane with a flux recovery percentage of 96.30%. Because of the efficient and appropriate performance of the UF-0.5 membrane, it was revealed that this membrane can be used as an effective UF membrane for the oil-water separation process, as well as in further studies.

防污型聚砜-氧化石墨烯超滤膜在水/油乳液分离中的高能力

本研究旨在合成氧化石墨烯（GO）纳米粒子，然后用三甲基氯硅烷（TMSCl）对其进行改性。改性后的 GO 被用于制造用于油水分离的聚砜-氧化石墨烯（PSf-GO）超滤混合基质膜。使用不同量的改性 GO 制备了 PSf-GO 超滤混合基质膜。使用各种技术，包括接触角测量、原子力显微镜（AFM）、傅立叶变换红外光谱（FT-IR）、X 射线衍射（XRD）和扫描电子显微镜（SEM），对合成的 GO 和制造的膜的结构、性能和特点进行了研究。对膜的油水分离性能及其防污亲和力进行了评估和比较。接触角测量结果表明，GO 纳米粒子的加入增加了膜的亲水性。在超滤过程中，UF-0.50（0.50%Wt GO@TMSCl）膜的水通量为 113.35 L/m2 h，油截留率为 97.44%，是所制备膜中性能最高的。膜污垢分析表明，这种膜的性能优于其他膜，这可能归功于纳米粒子的适当和均匀负载。UF-0.5 膜的防污性能最好，通量回收率为 96.30%。由于 UF-0.5 膜的高效和适当性能，该膜可作为一种有效的超滤膜用于油水分离过程以及进一步的研究。
