Membrane technology is known as one of the most efficient and extensive methods for oily wastewater treatment. In this research, polyvinyl chloride (PVC)-based mixed matrix membranes containing Uio66-NH2 nanoparticles and modified halloysite nanotubes (HNTs) were prepared using the phase inversion method. The synthesized membranes were characterized by FESEM, FTIR and contact angle measurement analysis. Then, the effect of these nanoparticles was investigated for oil/water emulsion separation in the ultrafiltration process. To evaluate the prepared membranes, pure water flux, mean pore size, and oil separation ultrafiltration tests were performed. The results showed that all the fabricated mixed matrix membranes had a good pure water flux. Overall experimental results showed that due to the uniform distribution of halloysite nanotubes, sample 2 has higher mean pore size, porosity, and pure water flux than other samples. UF results confirmed that sample 2 has the lower UF separation time and higher oily treatment efficiency compared to blank PVC.
