Abstract: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.
