With perfluorooctane sulfonate (PFOS) as the targeted matter and Bovine serum albumin (BSA) as the typical organic protein, we investigated the effects of BSA and its concentration, as well as ionic strength and ionic types when BSA coexisting with inorganic ions in feed water on PFOS removal by polyamide nanofiltration membrane in this study. The results showed that a significant improvement in PFOS removal rate was observed in the presence of BSA. The higher the concentration of BSA, the higher PFOS removal rate was. When BSA and inorganic ions coexisted in the feed solution, PFOS removal rate increased with the increase of ionic strength. This may be because BSA would not only absorb some PFOS, but also cause membrane fouling. The higher the BSA concentration, the more serious membrane fouling was. Consequently, the screening ability of fouled membrane and the electrostatic repulsion force between the membrane surface and PFOS were enhanced. Thus, the removal rate of PFOS increased. The existence of ions reduced the electrostatic repulsion force between BSA and the membrane surface, which resulted in thicker BSA fouling layers and enhanced membrane sieving capacity. Additionally, our experiments showed that the ability of Ca2+ to improve PFOS rejection was better than that of Na+.
