| 英文摘要 | Phyllosilicates with net negative surface charge and fe/al oxides with net positive surface charge coexist in variable-charge soils, and the interaction between these oppositely charged particles affects the stability of mixed colloids, aggregation, and even the surface chemical properties of variable-charge soils. the interaction of the diffuse layers of electrical double layers between the negatively charged soil colloidal particles and the positively charged particles of goethite or gamma-al2o3 was investigated in this article through the comparison of zeta potentials between single-soil colloidal systems and binary systems containing soil colloids and fe/al oxides. the results showed that the presence of goethite and gamma-al2o3 increased the zeta potential of the binary system containing soil colloids and fe/al oxides, which clearly suggests the overlapping of the diffuse layers in soil colloids and fe/al oxides. the overlapping of the diffuse layers leads to a decrease in the effective negative charge density on soil colloid and thus causes a shift of ph-zeta potential curves toward the more positive-value side. the interaction of the electrical double layers is also related to the charge characteristics on the fe/al oxides: the higher the positive charge density on fe/al oxides, the stronger the interaction of the electrical double layers between the soil colloid particles and the fe/al oxides.
