主　　题：surface complexation model Le An River sediment potentiometric titration adsorption. 

摘      要：In this study,the surface properties and adsorption properties of the Le An River sedi- ment were modelled via surface complexation *** model parameters were determined based on the data of our potentiometric titration experiments and the metal adsorption experiments with the Le An River sediment ***,the surface complexation models for the natural sediment,in our case the Le An River sediments,which can interpret the experimental data very well were successfully *** typical surface complexation models that is the con- stant capacitance model,the diffuse layer model and the triple layer model,were considered in this *** work indicated that the consistency and the interdependency among model parame- ters together with the selection of the surface adsorbed species should be emphasized.
