To demonstrate the applicability of the criterion, given by Eqs (5.8) - (5.10), Ay(t )-values of aqueous solutions containing decyl dimethyl phosphine oxide as the main component and dodecyl dimethyl phosphine oxide as the simulated impurity were measured. The results, shown in Fig. 5.4, confirm that the assumption works well.

To estimate this coefficient K, first the value of K can be determined experimentally, and the ratio D2/D1 calculated using the equation proposed by Wilke and Chang [229]. For CioEOg we obtain K = 1.8. For Tritons at the water/nonane interface the following values have been given [230] K = 1.5 for Triton X-45, and K = 0.5 for Triton X-100. For decyl dimethyl phosphine oxide (CioDMPO) the adsorption activity of which is close to that of CioEOg, a value of K = 1.3 was found by Ferrari et al. [133]. 

Decyl dimethyl phosphine oxide solution in water at 25 C [9]. The experimental data n vs t for this system measured at bulk concentrations 0.1 molW, 0.3 mol/m and 1.0 mol/m using MPT, TE and TVT methods are contained in the files C10DMPO-01R.txt, C10DMPO-03R.txt and C10DMPO-10R.txt, respectively. Figure 7.9 illustrates the results obtained for the system by calculations with WardTordai program. It is clearly seen that the experimental data obtained by various methods can be adequately approximated by the Frumkin model.

There are some informations about monotonous decrease of the equilibrium surface tension, dilatational elasticity, and adsorption of lysozyme for non-ionic surfactant decyl dimethyl phosphine oxide (Cj DMPO) as the concentration of surfactant increases in the mixture. However, in the case of mixtures of non-ionic surfactants with more flexible proteins like P-casein, the elasticity of the interfacial layer decreases before passing through a maximum as the concentration of surfactant increases [7], Possibly, the weaker interfacial network formed by P-casein as compared to globular proteins determines the dilatational response of the mixtures. The same picture was shown for the system P-casein mixed with dodecyl dimethyl phosphine oxide (C,2DMPO). For all studied frequencies (0.005-0.1 Hz) the elasticities for adsorption layers have a maximum about 4x10" mol/1 Cj2DMPO concentration. It was shown the obtained values are very close to those measured for the surfactant alone. Thus, in this concentration region the surfactant dominates the surface layer. In our case we have...
