Adsorption of sodium dodecyl sulphate on coal.

Czechia / Чехия

Simultaneous measurements of the sodium dodecyl sulphate (SDS) adsorption on coal and zeta potential determination of the (adsorption) suspensions were carried out. The adsorption isotherms were found to be of typical Langmuir type, values of the SDS adsorption capacities have been calculated. The results indicate that adsorption of SDS on coal is going mainly through hydrophobic interactions between the surfactant molecules and the coal surface.
