In this study, the oil-water mixture is separated with simple and low cost quantum dots metal for the first time by use of one-step Nano porous activated carbon (AC)/ Tungsten disulfide (WS2) quantum dots (QDs) stainless still mesh (SSM) as a super hydrophobic and petroleum-based substrate. Nano porous AC/WS2 QDs was synthesized and characterized by various XRD, FTIR, SEM/Map, TEM, BET-BJH, PL and CA techniques. The results show that the solvent type is also effective in the amount of its separation from oil. The effect of water-to-solvent ratio and pH was investigated. Based on the results of petrol with a water-to-solvent ratio of 40/20 at pH=7 and at a time of 14 seconds, 99.99% was separated by Nano porous AC/WS2 QDs/SSM with flux over 6000 L m−2 h−1. in order to investigate the effect of solvent of different water and solvent ratios, volumetric ratios of 20/20, 20/40 and 40/20 were examined as a mixture at pH=7. The results showed that the AC/WS2 QDs/SSM the repeatability cycle is 25 times and its duration to 30 seconds. The results of kinetic studies showed that the Pseudo second order kinetic model was in good agreement with the experimental data. https://jns.kashanu.ac.ir/article_112783_378251aa4f96ad42c4f7f7d27873ffd6.pdf
