研究土壤胶体的性质有着重要的意义,在许多土壤胶体的特性中,电化学性质是一个重要方面。大家知道,被分散在电解质溶液中的胶体颗粒,在与电解质溶液接触时,便产生了双电层,根据胶粒和溶液界面间游离电荷分布的机制,可以把土壤胶体区分为两种基
Studying the properties of soil colloids is of great importance. Among many characteristics of soil colloids, the electrochemical properties are an important aspect. As we all know, the colloidal particles dispersed in the electrolyte solution, when in contact with the electrolyte solution, produce an electric double layer. According to the mechanism of the free charge distribution between the colloidal particles and the solution interface, the soil colloids can be divided into two kinds of radicals
