โœฆ Synopsis

The electrophoretic mobility of a particle coated with an ionpenetrable charged membrane in a uniform electric field is investigated. In particular, the effects of the distribution of fixed charges and that of the dielectric constant in the membrane phase on the electrophoretic mobility are investigated. The results of numerical simulation reveal that these effects can be significant. In particular, for a constant total amount of fixed charges, assuming a homogeneous fixed charge distribution may lead to an appreciable deviation. 1995 Academic Press, Inc.

Key Words: Poisson-Boltzmann equation; electrophoretic mobility; planar particle; charged membrane; fixed charge distribution; dielectric constant distribution.

The dynamic electrophoretic mobility of a concentrated dispersion of biocolloids such as cells and microorganisms is modeled theoretically. Here, a biological particle is simulated by a particle, the surface of which contains dissociable functional groups. The results derived provide basic theory fo
