表面改性GOT/PVDF超滤膜的制备及对水中微污染物的去除
Fabrication of surface modified GOT/PVDF ultrafiltration membrane and its removal of micro-pollutants from aqueous solution
摘要
Abstract
The graphene oxide-TiO2 (GOT)/polyvinylidene fluoride(PVDF) ultrafiltration membranes were fabricated by coating GOT on PVDF membrane surface via dynamic filtration method.Humic acid (HA) and sulfadiazine (SDZ) were chosen as representatives of micro-pollutants in aqueous solution.The removal and membrane fouling of GOT/PVDF membranes were investigated during filtration of HA and SDZ under different light conditions.The stability of GOT on membrane surface was also studied.Results indicated that GOT/PVDF membrane could improve the removal of humic acid and reduce membrane fouling simultaneously.In photocatalytic ultrafiltration,98.3％ of SDZ was removed with GOT/PVDF membrane,which is much higher than the removal rate of 31.8％ under dark condition.关键词
