Original language name
Adsorption of SDS on coal
Original language description
Simultaneous measurements of the sodium dodecyl sulphate (SDS) adsorption on coal and zeta potential determination of the (adsorption) suspensions were carried out. Three samples of sub-bituminous, bituminous and oxidative altered bituminous coal were investigated. The adsorption isotherms were found to be of typical Langmuir type, values of the SDS adsorption capacities have been calculated. Shape of the adsorption isotherms was correlated with zeta potential values of the suspensions in (adsorption) equilibrium. The results indicate that adsorption of SDS on coal is going mainly through hydrophobic interactions between the surfactant molecules and the coal surface.
Czech name
Adsorpce SDS na uhlí
Czech description
Bylo provedeno paralelní měření adsorpce SDS na uhlí a zeta potenciálu suspenze. Proměřeny byly tři typy uhlí: černé, oxidačně alterované a hnědé. Adsorpční děj lze popsat Langmuirovou adsorpční teorií. Tvar adsorpčních isoterem korespondoval se změnamizeta potenciálu v průběhu adsorpce. Výsledky ukazují na hydrofobní interakce mezi povrchem uhlí a molekulami tenzidu.
