摘要: Abstract A relation between the dynamic electrophoretic mobility of spherical colloidal particles in a concentrated suspension and colloid vibration potential (CVP) generated by sound wave is obtained from analogy with corresponding Onsager sedimentation suspensions previously derived on basis Kuwabara's cell model. The expression for CVP applicable to case where particle zeta low, relative permittivity very small, overlapping electrical double layers adjacent negligible. It found that shows much stronger dependence volume fraction φ than predicted mobility. also suggested same holds electrokinetic sonic amplitude
