| 摘 要： | The kinetics of photocatalysis can be usually described by Langmiur-Hinshelwood adsorption expression.The adsorption can be greatly influenced by the surface properties of photocatalyst.Triple layer model(TML) was chosen to describe the surface adsorption of TiO2 based on electrical double layer(EDL theory at the TiO2/water interface.And through the potentiometric titration the parameters of TLM were determined by the extrapolation method and Fiteql3.1 software.The results show that surface complexation dominates the surface charge and the numerical calculation fits the experiment dtat satisfactorily.
