Chemistry, Physics and Technology of Surface| Резюме: | The results of the ring and the oscillating drop shape methods investigation of adsorption and surface rheological characteristics of natural polyelectrolytes–sodium humates solutions with additives of cetyltrimethylammonium bromide (CTAB) at a liquid–gas interface at different pH values are presented. The main features of concentration dependences of surface tension and visco-elasticity modulus for mixed sodium humates / CTAB solutions may be connected with the aggregate formation in the adsorption layer at appropriate CTAB concentrations. The possibility of foam formation from sodium humates / CTAB mixed solutions is studied. It was shown that pH reduction leads to an increase of foam stability. |
