The study of soil colloids is essential because the stability of soil colloidal particles are important processes of interest to researchers in environmental fields. The strong nonclassical polarization of the adsorbed cations (Na+ and K+) decreased the electric field and the electrostatic repulsion between adjacent colloidal particles. The decrease of the absolute values of surface potential was greater for K+ than for Na+. The lower the concentration of Na+ and K+ in soil colloids, the greater the electrostatic repulsion between adjacent colloidal particles. The net pressure and the electrostatic repulsion was greater for Na+ than for K+ at the same ion concentration. For K+ and Na+ concentrations higher than 50mmol L−1 or 100 mmol L−1, there was a net negative (or attractive) pressure between two adjacent soil particles. The increasing total average aggregation (TAA) rate of soil colloids with increasing Na+ and K+ concentrations exhibited two stages: the growth rates of TAA increased rapidly at first and then increased slowly and eventually almost negligibly. The critical coagulation concentrations of soil colloids in Na+ and K+ were 91.6mmol L−1 and 47.8mmol L−1, respectively, and these were similar to the concentrations at the net negative pressure.
