    pH and Ionic Strength Effects on Crossflow Microfiltration of TiO2 Dispersions

  • Original language description

    The interfacial effects between TiO2 particles and the particle interactions between TiO2 particles and the surface of Al2O3 membrane have a significant influence on cross-flow microfiltration of TiO2 suspensions. Zeta potential is very important electrochemical property, which describes the interaction between particles. The zeta potential can be easily varied through a change of the pH value and also through a change of the ionic strength of the suspension.The aims of this work are to measure the intensity of permeate flux as a function of pH, salt and salt concentration and study the influence of these parameters on the separation efficiency.

    Vliv pH a iontové síly na průběh mikrofiltrace disperze TiO2

  • Czech description

    Vzájemné působení částic TiO2 a interakce mezi částicemi TiO2 a povrchem membrány z Al2O3 mají významný vliv na průběh cross-flow mikrofiltrace disperze TiO2. Zeta potenciál je významná elektrochemická veličina, která tyto interakce popisuje. Zeta potenciál může být jednoduše měněn změnou pH a změnou iontové síly disperze.Cílem této práce je zjistit závislost intenzity toku permeátu na pH, druhu soli a koncentraci soli.
