Synthesis and Interaction Investigation of a Non-ionic Surfactant in Aqueous Medium at Different Temperatures

Abstract

The surface tension data have been utilized for evaluation of surface and thermodynamic parameters. Isooctylphenoxypolyethoxy ethanol (TX-100) with/without aqueous Na₂SO₄ has been reported at 288.15, 293.15 and 298.15 K. Thermodyanamic parameters indicate that processes are endothermic in nature but negative values of DG⁰_mic and positive DS⁰_mic favours the process of micellization.
