Effects of Interactions Between Surface Charges and Ions on Conductance of Variably Charged Soil

LUO Ting,SHI Hui-yu,LI Hang School of Resources and Environment,Southwest University 400716,China  
Conductance determination has been widely applied to the study of soil science and may become a useful approach to revealing the interactions between colloidal particle surface and solution ions. Through the determination of electrical conductivities and pH in soil suspensions and aqueous solutions at different KNO3 concentrations,some interesting interaction effects between the particle surface of a variably charged soil and solution ions were observed. The number of variably negative charges on the soil particle surface increased with increasing electrolyte concentration in soil colloidal suspension and,as a result,the suspension conductance increased. Because of the hydrolysis of KNO3,the higher the KNO3 concentration was,the lower pH values would be in the soil colloidal suspension. It seemed that the key factor influencing the numbers of negative charges for variably charged particles was not pH but the relative competition between H+ and base ions physically adsorbed on the particle surface. In other words,lower pH did not necessarily lead to a decrease in the number of negative charges on the soil particle surface. Therefore,the indirect effects of the hydrolysis of the electrolyte on the surface charges should not be neglected in the study of the effect of electrolyte on surface charges of variably charged particles.
