The Influence of Inorganic Ions on the Zeta-potential of Titanium Dioxide Dispersion and Its Microfiltration Process

Original language description

Effects of inorganic salts on ceramic membrane microfiltration of TiO2 suspensions were studied. A series of crossflow microfiltration experiments were carried out at various pH values, ionic strengths and with various multivalent inorganic salts. Filtration behaviours were analyzed based on measurements of particle size distribution of the TiO2 suspension, zeta potential of alumina membrane and TiO2 particle. Results showed that inorganic solution salts affect the microfiltration of TiO2 suspension bychanging the surface properties of both the alumina membrane and TiO2 particle. The solution environments affect the dispersion of TiO2 particles and played a major role in the filtration flux. The aim of this work is measuring of the intensity of permeate flux as a function of pH, various multivalent inorganic salts, salt concentration, and the study of the influence of these parameters on the separation efficiency, respectively.
