Adsorption Behavior of Oxyethylated Surfactants at the Air/Water Interface

Interfacial tensiometry as a novel methodology for the determination of surfactant adsorption at a liquid surface

“…Note that the uncertainty in the experimental values arises mainly from the error related to the measurement of equilibrium surface tension, which amounts to an absolute error of about 0.5 mN/m for each of the methods used. Possibly, a more detailed analysis of the adsorption mechanism could be based on studies either of alkyldimethylphosphine oxides of longer alkyl chains, or of oxethylated surfactants, as for these systems the difference between the adsorption values predicted by various models becomes more pronounced; see [9,10]. In Fig.…”

“…Fitting of Eqs. (4)- (10) to the experimental isotherm measured by the ring method (Fig. 2) was performed by the software given in [12].…”

Equilibrium and dynamic surface properties of trisiloxane aqueous solutions. Part 2. Theory and comparison with experiment

“…Reorientation model (or two-state model) describes well adsorption behaviour of different oxyethylene surfactants on liquid-air interfaces [2][3][4][5][6]. At low surface concentrations both carbohydrate and oxyethylene groups of those surfactants adsorb simultaneously.…”

Effects of dodecanol on the adsorption kinetics of SDS at the water–hexane interface

“…The major amount of potential impurities in SDS samples is the homologous alcohol dodecanol (C12OH) [13]. Compared to SDS, C12OH is only slightly soluble in water and about 400 times higher surface active at the water/air interface [14]. The effect of dodecanol on the co-adsorption with SDS from aqueous solutions at the air/water interface has been investigated by various methods, such as surface pressure measurements at equilibrium and dynamic conditions, Brewster angle microscopy (BAM) and Grazing incidence X-ray diffraction (GIXD) [15][16][17].…”
