Procedure

Values of α reported for a number of anionic surfactants at air-waterand heptane-water interfaces range from 45 to 72 Å2 . Oh and Shah estimated α of sodium dodecylsulfate at hexadecane/water and air/water interfaces as 68.9 and 5.18 Å2 respectively. Sodium dodecylbenzosulfonate (SDBS), an anionic surfactant, exhibited saturation adsorption on graphon, a hydrophobic surface, at the CMC, with α value of 60 Å2. We obtained α value of 61 Å2 for SDBS at decane-water interface, from a plot of interfacial tension, γ, versus the lnC, using the Wilhelmy plate technique for measuring γ.
