Název v původním jazyce

The Influence of Cl-, SO42- and PO43- Ions on the Zeta-potential and Microfiltration of Titanium Dioxide Dispersions

Popis výsledku v původním jazyce

In this paper the influences of pH and ionic strength 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 zeta potential of alumina membrane and TiO2 particle and particle size distribution of the TiO2 suspension. Results showed that inorganic anions affect the microfiltrationof TiO2 suspension by changing 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 filtration behaviours were analyzed based on measurements of the permeate flux as a function of pH, various inorganic salts, and salt concentration. Special attention was given to the study of these parameters on the separation efficiency.
