Details

Zeta potential of the particle is calculated using the Henry's equation by calculating the electrophoretic mobilityof a particle in an electric field through the following equation is: UE =2  z f (ka)/3h z :Zeta potential,UE :Electrophoretic mobility, :Dielectric constant, :Viscosity, f(ka) Henrys function
