Der Einfluß der Struktur polyoxypropylierter sekundärer Amine auf ihre Adsorption an der Grenzfläche Wäßrige Lösung-Luft / Structural Effects of Polyoxypropylated Secondary Amines on their Adsorption at the Aqueous Solution - Air Interface

Copper doped graphene-TiO2 nanocomposite were prepared via sol-gel process and embedded onto ITO coated glass films using electrophoretic deposition technique. The catalyst films were used for photoelectrocatalysis (PEC) of CO2 induced under simulated solar irradiation. Triethanolamine (TEA) aqueous solution was used as an electrolyte in this experiment. CO2 capture in the electrolyte solution plays vital role in the PEC process and in this case, the effect of TEA was investigated. Although the absorption rate of CO2 is lower in TEA solution than primary or secondary amines, CO2 loading was found higher in the solution. Less reactivity of TEA towards CO2 was also observed. The impedance results showed that, increased concentration of TEA in aqueous solution helps to reduce charge transfer resistance and thus facilitates CO2 reduction process.

Measurements of the surface tension of the aqueous solution of SDDS mixture with fluorocarbon surfactants (FC) were carried out and considered in light of the surface tension of aqueous solutions of individual surfactants. Similar analyses were made for many other aqueous solutions of binary and ternary mixtures, taking into account the literature data of the surface tension of aqueous solutions of TX100, TX114, TX165, SDDS, SDS, CTAB, CPyB and FC. The possibility of predicting the surface tension of the aqueous solution of many surfactant mixtures from that of the mixture components using both the Szyszkowski, Fainerman and Miller and Joos concepts was analyzed. The surface tension of the aqueous solutions of surfactant mixtures was also considered based on the particular mixture component contribution to the water surface tension reduction. As a result, the composition of the mixed surface layer at the solution–air interface was discussed and compared to that which was determined using the Hua and Rosen concept. As follows from considerations, the surface tension of the aqueous solution of binary and ternary surfactant mixtures can be described and/or predicted.
