The colloidal surface-active substances (CSAS) are capable to form molecular solutions only at very small concentrations. The greatest possible concentration, when CSAS is still in solution in the molecular (ionic) form, for the CSAS majority lies in the limits of 10-5-10-3 mol/l. More concentrated of them gain colloidal structure owing to formation in a volume of solution of aggregates - micelles. This phenomenon makes up the CSAS most important distinctive singularity, many practically valuable properties of their solutions are connected with which one.It is shown, that at an adsorption of CSAS on technical carbon and magnetite a formation of resistant suspensions, at concentrations exceeding critical concentration of micelleforming is observed. It is established, that in micelles of CSAS depending on nature of the used adsorbent one and more fragments of the adsorbent can be colloidal dispersed.
