采用电导滴定法研究了恒电荷土壤胶体表面的电导特性 ,提出了几个特征参数 :表观碱量电导率、表观碱量电导贡献率 ,这些参数是氢铝离子与胶体亲和力、碱金属阳离子在土壤胶体表面解离度及离子自身导电能力的综合表征。电导滴定法测定的阳离子代换量 (CEC)与滴定体系有关
The conductance titration method was used to study the conductance characteristics of the surface of constant charge soil colloids, and several characteristic parameters were proposed: apparent alkali conductivity and apparent alkali conductivity contribution. These parameters are the affinity between hydrogen and aluminum ions and colloids, alkali metal cation The comprehensive characterization of the dissociation degree on the surface of soil colloids and their own conductivity. Cation exchange capacity (CEC) measured by conductometric titration is related to the titration system
