The influence of inorganic ions on the ζ-potential of titanium dioxide dispersion and its microfiltration process

Photocatalytic activity of size and phase selective TiO2 nanoparticles prepared by the membrane processing

“…The membrane separation technique as one kind of fractionating techniques is receiving more and more attention due to its advantages of high efficiency, and easy operation, and furthermore, it is a green process. Many kinds of membrane methods such as the ceramic microfiltration (MF) [12][13][14][15][16], polypropylene (PP) and polyethylene (PE) tubular MF [17], and blend polysulfone and dichlorodiphenylsulfone (PS-PDC) ultrafiltration (UF) [18] were used to recover and concentrate TiO 2 particles from aqueous TiO 2 suspensions. But, up to now, the research on fractionation of polydispersed TiO 2 nanoparticles via membrane processing is seldom reported.…”
