Zeta potential is the charge on a particle at the shear plane. This value of surface charge is useful for understanding and predicting interactions between particles in suspension. Manipulating zeta potential is a method of enhancing suspension stability
In another method of analysis, the sample was suspended in DI (deionized) water without buffer by varying pH from 2 to 8 for the measurement. A linear relationship between and pH was obtained together with the constant value k (slope) which could be converted into protein content (x) of ...
紧密层和扩散层相接的地方存在一个滑移层(处于距离紧密层朝外方向很短的地方),大致地我们可以这样认为:粒子在水中运动的时候,滑移层左侧的离子都能跟随粒子一起运动,而其右侧的粒子则没有那么'死心塌地'地跟它走,所以两者之间会产生滑动。在此处,Zeta电位指的就是水相中固体粒子的滑动面相对于远处(即离子平衡处)...
An almost forgotten technique, the streaming potential method, experiences its revival. The aim of the streaming potential measurement is the assessment of the surface charge at the material-water interface. The charging behaviour is described by the zeta potential, a parameter well known for the ...
