Eleven geographically and hydrologically diverse sediment samples were collected from major rivers of China and determined for the surface properties. The results indicate the sediments have a large variation in surface area (6.9-16.0 m(2)/g of SSA(N2), 35.6-73.2 m(2)/g Of SSA(CPB), surface site density (10.3-149.8 mu mol/g) and surface acidity constants (1.56-2.50 of pK(s.a1)(int), and 3.75-5.58 of pK(s.a2)(int)) but a small difference in PZSE (3.0-4.0). Within the pH range 3.0-9.0, all sediments present negative surface charges. Their surface charge distribution curves with pH extend between these of SiO2, montmorillonite. kaolinite, alpha-MnO2, calcite and gamma-Al2O3;. Correlation analysis reveals that surface area and surface site dens...
