This article considers electro-optical effects in liquid disperse systems with particles comparable with the wavelength of light and exceeding it. Criteria are introduced that allow splitting the extinction constant of particles into two parts, characterizing small (Rayleigh) and larger particles. Using the example of studying diamond and graphite hydrosols containing particles of different sizes, it is demonstrated that the electro-optical method associated with the determination of two distinct effects from the intensity of light passed through a dispersed system (which are pronounced for both small and large particles), is applicable to dispersed systems with a wide distribution of particle sizes. The method is effective in studying the processes of formation of aggregates in dispersed systems and analyzing their stability.
