Abstract

The surface tension of the aqueous solution of 2-(octylsulfinyl)ethanol and decylammonium chloride mixture has been measured by changing the total molality and composition of surfactants at 298. 15 K under atmospheric pressure. It has been observed that the surface tension decreases with increasing the total molality at a constant composition and with decreasing the composition of decylammonium chloride at a constant total molality. Further the surface tension vs. total molality curve has been found to have a break point at a relatively low concentration. Thermodynamic equations have been developed so as to be applicable to the adsorption of nonionic-ionic mixture and used to calculate the surface density and the surface composition.
