What is Adsorption of Sodium Dodecyl Sulfate and Butanol onto Acidic and Basic Alumina about?

## Aluminum oxides have been especially useful in such The adsorption of sodium dodecylsulfate (SDS) and the costudies since their surface charge and electrical double adsorption of SDS and 1-butanol from aqueous electrolyte solulayer properties are well characterized and controlled by tions and from microemulsions containing heptane onto acidic the pH (3, 4). ## and basic aluminum oxide were measured. The aluminum oxides In contrast to the large amount of literature on surfaccontain quasi-spherical highly porous particles with an amorphous tant / cosurfactant association and micellar solubilization, structure. The measurements were carried out just above the considerably less work has been done on adsorption at Krafft temperature at 26ЊC. It is shown that the adsorption capacity of SDS and butanol onto the acidic alumina is slightly higher solid / liquid interfaces of surfactant systems containing than that onto the basic. The adsorption of SDS decreases while additives. However, some previous papers have investibutanol adsorption increases upon increasing alcohol concentragated the mutual adsorption of anionic surfactants and tion. The alcohol to surfactant mol ratio on the oxide
