Effect of TiO₂ Concentration on Structure and Performance of Polysulfone Hollow-Fiber Ultrafiltration Membrane

Abstract:

In order to prepare polysulfone (PSF) hollow-fiber ultrafiltration (UF) membrane with ideal hydrophilicity, TiO₂nanoparticle was introduced to casting solution. Furthermore, the effect of TiO₂nanoparticle concentration on structure and performance of membrane were investigated. It was found that with the addition of TiO₂ nanoparticle, the structure and performance are influenced obviously. With the increase of TiO₂ concentration, the porosity increase, the tensile strength and fracture length have maximum values when TiO₂ concentration is 1 wt%. The water flux increase obviously and the retention rate decrease slowly with the increase of operating pressure, considering water flux and retention rate of the membrane, the best operating pressure is 0.2 MPa.
