| 제목 | The effect of UV radiation on NF composite membrane adding TiO2 photocatalyst |
| 초록 | The effect of UV radiation on NF composite membrane adding TiO photocatalyst 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 added to Polyethersulfone(PES) when we made UF membranes as the substrates of TiO-NF composite membrane. TiO-NF composite membranes were modified by different manufacturing conditions and varying the ratio of TiO. We've been studying the performance for photocatalytic decomposition under UV light for the purpose of a high water flux and the rejection of bivalent anion salt The characterization of membranes were appiled on conductivity, FT-IR, NMR, XRD, SEM and so on. |
