Summary:The linearized Poisson-Boltzmann equation is used to estimate the radial distribution of potentials in a coaxial capillary and confirmed by experimental data. ξ-potentials are estimated for a capillary column with a sorbent containing magnetic nanoparticles. The thermal power in the column is calculated on the basis of the strength of an electric field with a certain electric conductivity. The column heating is calculated taking into account a thermal effect of the electric field for two estimates of the thermal diffusivity coefficient in the radial cross-section of a column comprising two layers of compounds with different physical properties.
