中文摘要：

以聚酯工业滤布为基膜,采用溶胶凝胶和浸渍方法制备了具有吸附-光催化功能的多壁碳纳米管（MWNTs）/TiO2涂层的复合膜,该复合膜对模拟水样低浓度（10mg/L）的双酚A具有较高吸附性能.随着复合膜上负载二氧化钛中的MWNTs的比例（17.6%,29.9%,和46.0%）增加,吸附去除率显著提高;吸附饱和的复合膜上的污染物双酚A可通过20W紫外灯（λ=254nm）照射Fenton氧化反应去除.吸附实验和HPLC分析表明,除了超声处理会引起浸渍负载的材料脱落外,复合膜吸附性能恢复较好.

英文摘要：

Series of composite functional membranes, containing adsorptive multi-walled carbon nanotubes（MWNTs）, and photocatalytic TiO2, based on polyethylene （PET） filter cloth, were prepared by using a sol-gel and dip-coating method. The membrane could remove low concentration （10mg/L） BPA （bisphenol A） efficiently from simulate polluted water sample. With the proportional increase of MWNTs to MWNTs＋TiO2 （17.6%, 29.9%, 46.0%）, removal rate of BPA increased accordingly. The adsorbed BPA on the saturated membrane could be removed by 2h （20W 254nm） UV-Fenton oxidation reaction. Repeated adsorption and HPLC analysis proved that the adsorption capacity of the studied membrane could be regenerated successfully, despite the detachment of MWNTs/TiO2 occurred when ultrasonically treated.
