The majority of toners concerns to polymeric highdispersion composite materials which properties largely depend on compatibility of components included in their structure.To characterize interaction, displayed in a polymeric composition adsorption of components present in a mix at toner manufacturing by us is carried out. It's determined the quantity of colloidal dispersion of high-dispersion adsorbents in a colloidal solution of surface-active substances. Adsorption of polystyrene was not complicated by the phenomenon of colloidal dispersion in connection with that, that in quality of adsorptive the samples of polystyrene of rather low molecular weight (2.0·105) were used. With increase of equilibrium concentration under adsorption of polystyrene from a solution of toluene on technical carbon or magnetite the sharp increase of adsorption is observed, we connect it with adsorption of macromolecules.Adsorption of nigrosine was carried out from two solvents: toluene and chloroform. For equilibrium concentration definition we used a photometry method. It was established, that nigrosine is dissolved in chloroform better then in toluene. Under adsorption of dye with toluene the change of solutions coloring is observed. It is connected with such fact, that the adsorption of blue-black component of nigrosine is better, than that red - black one.
