摘要：
The article deals with talc absorbing capacity of Onotsk deposit (Irkutsk region). Absorbing capacity of the mineral is measured by absorption of aqueous solution in a wide range of concentrations of sodium oleate. The author shows that the extent of sodium oleate adsorption increases significantly because of the increasing temperature and decreasing pH. The effect of pH on the process of absorption is ascertained. The highest extent of the adsorption in the acidic medium is shown. The author determines the idea of the adsorptive mechanism that involves the options of monomolecular filling of the surface and accompanying process structurization (salvation, creation of micellae and vesicles).
