| Tartalmi kivonat: | The forming agents Supragil WP (anionic) and CTAB (cationic) were investigated in model soil solution systems because these compounds are frequently used in different products (pesticides, vaccines, cosmetics etc.) that can become environmental contaminants. The colloidal system was characterized by surface tension and zeta potential measurements. The humic substances form associates with both agents and the system is able to be stabilized either with negative (in case of Supragil) or with positive charge (in case of CTAB). This indicates the risk of the application of these compounds especially near either to the groundwater level or to any surface water. Adsorption of Supragil on different soils resulted in two-step of isotherms. The formation of two layers is indicated also by zeta potential measurements. |
