We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper. The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org. PAHs, which have a disrupting effects on human's health, is increasingly noticed in aquatic environment. And it is essential to find an efficiency way to remove PAHs from water. By contrast, nanofiltration technology is a better way than traditional methods. This paper offers a study on the impact of ionic strength, pH and adsorption on the PAHs (naphthalene, phenanthrene and fluoranthene) removal by nanofiltration membrane. The experimental results indicated that there is a higher flux by BDXN-70 NF membrane than by BDXN-90 NF membrane and the rejection of PAHs relatively efficiency for BDXN-70 membrane. The trace PAHs in water could be better rejected (rejections are more than 95%) by nanoflltration membrane stability at acidic solutions. There is little influence of rejection on the different ionic strength except naphthalene. Moreover, there is a large adsorption in the beginning and it declines significantly at the later time. After 6 h, it is seemed to have reached saturation. Then the rejection will maintain constant until the membrane were fouled seriously.
