Figure 9.30. (a) Adsorption isotherm of sodium dodecyl sulfate (SDS) on alumina at pH 6.5 in 0.1 M NaCl. (b) Zeta potential of alumina as a function of equilibrium concentration of SDS (designation of regions based on isotherm shape). (From Chandar et al., 1987 based on the data of Somasundaran and Fuerstenau, 1966.) Chandar et al. (1987) have shown with the aid of fluorescent probe studies that in region II and above adsorption occurs through the formation of surfactant aggregates of limited size. 

Residual foam heights are seen to be invariant at low values of p as predicted by Equation 4.41 where drop sizes are constant regardless of solution compositions. , Solutions containing sodium dodecyl polyoxyethylene sulfate , solutions containing SDS. (b) Measurement of residual foam height.
