摘要：

This paper investigated the effects of different pH and dispersant concentration on the dispersion of TiO2-H2O by the measuring zeta potential and absorbency. The results show that the absolute value of zeta potential and the absorbency are higher at pH approximate to 8-10. Sodium dodecyl sulfate (SDS) can significantly increase the absolute value of zeta potential of particle surfaces by electrostatic repulsions, which leads to the enhancement of the stability for TiO2 nano-suspensions. 0.1%(Mass fraction) TiO2 nano-suspensions has the best dispersion at the SDS optimizing concentration 0.045 %. The results also show the zeta potential has good corresponding relation with absorbency, and the higher absolute value of zeta potential and the absorbency are, the better dispersion and stability in system is.
