Ss. Dukhin et al., NONLINEARITY OF ELECTROPHORESIS CAUSED BY THE MOBILITY OF ADSORBED IONS - THRESHOLD VALUE OF THE EXTERNAL-FIELD, Colloid journal of the Russian Academy of Sciences, 55(6), 1993, pp. 804-812
The threshold value of the external field strength was estimated by so
lving the problem of the linear (with respect to the external field) p
olarization of the compact part of the electric double layer of a sphe
rical particle. It was shown that for 10-mu particles for E approximat
ely 100-1000 V/cm (as a function of the mobility of the adsorbed ions)
, nonlinearity of electrophoresis should appear due to lateral transpo
rt of ions adsorbed on the surface of the particle.
