摘　　要：引入流动电流(Streaming Current,简称SC)这一重要电动化学参量,研究了在天然浑浊水中SC的基本模式,提出了SC与水中悬浮胶体颗粒表面电荷量及无机阳离子之间的理论关系,探讨了离子的浓度、性质、存在环境等对体系电动特性的影响,并对水中常见8种阳离子共存条件下的电动化学特性进行了实验分析,从而建立了无机阳离子对胶体的聚沉能力与电动响应特性之间的实际联系.Introducing streaming current (SO as the essential parameter of electrokinetic characters ,this paper presents the equation for SC relating to the charges of colloid particles and cations in natural water. The affect of ion concentration, property and existing environment on electrokinetic chemical characters is studied. Further more, the investigation about electrokinetic chemical characters in the condition coexisting 8 cations also is carried out by experiments, so that the practical relationship between the coagulation ability of cations on colloid particles charged negatively in natural water and electrokinetic parameters is set up.
