Abstract

A nano-structured TiO2 membrane having desired pore structure has been prepared by the anodization treatment of micro-porous tubular type pure titanium filter. The anodized nano-structured TiO2 membrane was found to act as photocatalyst and decompose N-nitrosodimethylamine (NDMA) efficiently under UV irradiation. This UV/anodized TiO2 membrane process realized the complete removal of NDMA with 20 mg L−1 concentration, indicating that this process can be a promising technology for the purification of NDMA contaminated water.
