TiO-NF composite membrane has some unique characteristics such as high water flux, semiconducting properties, photocatalysis and chemical resistances over other membranes. Most of photocatalyst used as a pure powder form has the problems of withdrawl and light shield by particles. therefore the manufactured NF composite membrane can perform photocatalytic reaction and seperation simultaneously by means of TiO photocatalyst attached to NF composite membrane surface. In this work, TiO photocatalyst were deposited to membrane surface when we made PA active layer.TiO-NF composite membranes were modified by different curing conditions and varying the ratio of TiO. We've been investigating the performance for photocatalytic decomposition under UV light for the purpose of the rejection of humic acid. The characterization of membranes were appiled on ion conductivity, FT-IR, AFM, XRD, SEM. |
