The adsorption properties of short chain alcohols and Triton X-100 mixtures at the water–air interface

Ancillary effects of surfactants on filtration of low molecular weight contaminants through cellulose nitrate membrane filters

“…(1) are 3.86 × 10 −2 , 3.33 × 10 −2 and 2.97 × 10 −2 mol/cm 2 for the SDS, CTAB and TX-100, respectively. The literature values for the same surfactants are 4.76 × 10 −2 , 3.10 × 10 −2 and 2.83 × 10 −2 mol/cm 2 [22][23][24]. The respective parking areas calculated from these densities are 0.43, 0.49 and 0.55 nm 2 per molecule for these surfactants.…”

Wettability of quartz in presence of nonionic surfactants and short chain alcohols mixtures

“…Curves 1-7, correspond to the constant values of TX-100 concentration (C 1 ) equal to 0, 10 À7 , 10 À6 , 10 À5 , 10 À4 , 6 Â 10 À4 and 10 À3 M, respectively. wettability were observed in the range of alcohol concentration at which they were present in monomeric form in the solution [32][33][34][35]. The shape of the contact angle-alcohol molar fraction (X 2 ) curves for a given alcohol was nearly the same for the series of aqueous solutions of TX-100 and TX-165 with alcohol mixtures.…”

“…The All values of the adhesion work corresponding to the alcohol concentration range at which it is present in the solution in the monomeric form [32][33][34][35] changed from the work of water adhesion to the work of alcohol adhesion to the quartz surface. However, above the concentration at which the aggregation of alcohol occurs [32][33][34][35] the work of adhesion calculated from contact angles is lower than that of alcohol adhesion to the quartz surface.…”

Adsorption of Triton X-100 and cetyltrimethylammonium bromide mixture with ethanol at nylon-6–solution interface with regard to nylon-6 wettability: I. The effect of adsorption on critical surface tension of nylon-6 wetting

“…The multicomponent surfactant systems are usually applied because they often show a synergetic effect in the water surface tension reduction in comparison to the single-surfactant solutions at the same concentration (Rosen 2004;Szymczyk 2011Szymczyk , 2012Szymczyk and Jańczuk 2010;Bielawska et al 2012). Moreover, there are many organic and inorganic additives which can modify the volumetric and surface properties of the wetting liquid and the short-chain alcohols like methanol or ethanol are the most popular among them (Rosen 2004;Zana 1995;Zdziennicka 2009aZdziennicka , 2010a. Depending on their concentration in the solution they can be treated as cosurfactants or cosolvents and their activity at the solidsolution interface is strongly related with the number of the carbon atoms in their chain and its branching (Rosen 2004;Zana 1995;Zdziennicka 2009aZdziennicka , 2010b.…”

Taking the literature data into account (Zdziennicka 2009b, Zdziennicka and, it seems that the addition of the shortchain alcohol to the aqueous solutions of the mixture of two classical surfactants may strongly improve the wettability of the solid by these solutions by enhancing the synergetic effect in the water surface tension reduction.…”
