%X Titration was used to study the surface acid-base characteristics of a Chinese loess sample at different concentrations of supporting electrolyte. The acidimetric supernatant was considered as the system blank to compensate the influence of particle dissolution and complex reactions between soluble components on estimation of proton consumption. The simulation results of two simple surface complexation models indicated that the constant capacitance model and the diffuse layer model were applicable to the high ionic strength (0.1*!mol/L) and to the low ionic strengths (0.01 and 0.005*!mol/L), respectively.
