N2 - The dispersion of the electro-optical effect in polydisperse hydrosols of diamond is studied in the external field frequency ranging from 10 Hz to 2.5 MHz. The conservative dichroism, which is determined by the difference in the turbidity constants for light polarized along and perpendicular to the particle-orienting field, is chosen as the electro-optic effect. The dispersion dependences of the dichroism are determined and used to calculate the dispersion of the average values of the polarizability anisotropy of the diamond particles. The influence of the concentration of monovalent ions in an aqueous KCl solution on these dispersion dependences is studied. The experimental dependences of the dispersion are compared with the theoretical ones within the model of the polarizability of the colloidal particles which takes into account the polarizability of the diffuse part of their double electric layer.
