摘要
The TiO2 hydrosols studied in this work were synthesized by hydrolysis of titanium tetraethoxide according to Zukoski's method. Critical coagulation concentrations (CCC) were measured for pH values ranging from 2 to 12 in the presence of various monovalent ions. The observed ionic adsorption sequences are explained in terms of an extension of Gurney concept of ion-ion interactions. The influence of the volume fraction of the solid is also reported and explained by the coagulation-repeptization theory.
