| Abstract | SummaryThe role of surfactant concentration on the lowering of interfacial tension of benzene — water system has been observed and from the data obtained, the surface pressure, area and the surface excess of the different surfactants have been calculated, usingGibb's adsorptions equation. The surface pressure — area isotherms were constructed.Cationic surfactants were more strongly adsorbed at the oil-water interface than anionic ones, showing their greater efficiencies. The order of the efficiencies for cationic detergents was CDBAC > CTAB > CPB > LPC and for anionic detergents it was OSS > SAS > SLS > BSS. The results have been explained on the basis of the chain length and head group size of the surfactant molecules.ZusammenfassungEs wird der Einfluß kationischer und anionischer Tenside auf die Grenzflächenspannung Benzol/Wasser gemessen und mit Hilfe derGibb'sschen Gleichung die Grenzgflächenkonzentration der Tenside berechnet. Die Wirksamkeit der kationischen Tenside nimmt in der Reihe ab: CDBAC > CTAB > CPB > LPC und die der anionischen Tenside in der Reihe: OSS > SAS > SLS > BSS. Die Ergebnisse werden im Zusammenhang mit kettenlänge und Größe der polaren Endgruppen diskutiert. |
