Abstract：

Ibuprofen, a kind of environmental micro-pollutants has been studied by nanofiltration in view of nanofiltration process, solution chemistry and pre-contact time. The results showed that the membrane permeate flux increased with the increased pH. The nanofiltration membrane has kept high retention efficiency due to the higher ionization degree at higher pH. The membrane flux has decreased dramatically with the presence of NOM and the higher retention can be obtained while the adsorption quantity decreased. The longer pre-contact time will affect initial flux and has no big effect on the accumulative adsorption quantity of IBU.
