Abstract :In this study, polylactic acid insert ignore into journalissuearticles values(PLA);-based nanocomposite membranes were prepared and used for the purification of simulated oil/water based wastewater. The lubricant oil insert ignore into journalissuearticles values(lubricating oil); was chosen as model oil. In order to increase the hydrophilicity of the membrane and improve its filtration performance, 0-20 wt.% of Halloysite nanotubes insert ignore into journalissuearticles values(HNT); were added into the PLA matrix. The effects of the HNT ratio on the oil/water swelling ratios insert ignore into journalissuearticles values(adsorption ratio);, water flux, and oil rejection were determined. According to the results, optimal flux-oil rejection results were obtained with 5 wt.% of HNT incorporated nanocomposite membranes. The highest oil rejection of 94.9% was obtained using 5 wt.% of HNT incorporated membrane with a flux value of 1542.9 LMH.
