Dynamic Surface Tensions of Aqueous Surfactant Mixtures: Experimental Investigation

摘要: We present an experimental investigation of the interfacial behavior aqueous solutions two nonionic surfactants and their binary mixture. Specifically, we measure both equilibrium surface tensions (using Wilhelmy plate method) dynamic pendant bubble technique) alkyl ethoxylate surfactants, dodecyl penta(ethylene oxide) (C12E5) decyl octa(ethylene (C10E8), as well These measurements are then compared with predictions made using recently developed molecular-thermodynamic theories behaviors surfactant mixtures found to be in good agreement. The main advantage adopted here is that they based on molecular characteristics such, required number experimentally determined parameters can reduced significantly. Indeed, no e...
