The electrophoretic mobility and adsorptive properties of kaolin and kaolin pretreated with anionic and cationic materials were examined over a range of pH values. Pretreatment with anionic compounds had little effect on mobility, while adsorption of cationic species markedly reduced mobility. These results are explained by reference to the structure of kaolin, and the interdependence of adsorption properties and electrophoretic mobility are discussed.
研究了高岭土以及用阴离子和阳离子材料预处理过的高岭土在一系列pH值范围内的电泳迁移率和吸附特性。用阴离子化合物预处理对迁移率影响不大，而阳离子物质的吸附则显著降低了迁移率。通过参考高岭土的结构对这些结果进行了解释，并讨论了吸附特性与电泳迁移率之间的相互依存关系。
