In the surfactant rich phase of ATPS or in the adjacent stoichiometric state of ATPS, the system has high viscosity because of its long range ordered structure.
Experimental investigations reveal two symmetrical aqueous two-phase systems (ATPS) in ternary phase diagram of SDS/CTAB/H2O system. The rheological properties and microstructure were investigated using a rheostat and freeze-fracture technique and are shown to be closely related to the phase behavior. Phase behavior of mixed sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB) aqueous solution were studied. Qingdao 266042, Shandong, China **College of Chemistry and Environmental Engineering, Shangdong University of Science and Technology *College of Chemistry and Molecular Engineering, Qingdao University of Science and Technology RHEOLOGY AND MICROSTRUCTURE STUDIES OF SDS/CTAB/H2O SYSTEM This simulation was made at the University of Colorado Boulder, Department of Chemical and Biological Engineering. This simulation runs on desktop using the free Wolfram Player. Ternary phase diagrams can also be drawn using mole fractions instead of mass fractions. The fraction of the distance from the base to the corner is the mass fraction of that component. In the “alternate view”, the mass fraction of a component is determined by drawing a line through the point and perpendicular to the base opposite that component. These axes are labeled by drawing a line through the point this line is parallel to the base of the triangle that is opposite the corner corresponding to that pure component. The mass fraction of a component in the mixture is read off the axis that is the same color as that component in the standard view.
Each corner of the triangle corresponds to a pure component. Move the black dot to any location within the triangle by clicking on that location, which represents the overall composition of the mixture. This simulation shows two representations of a ternary phase diagram, which is used to represent the phase behavior of three-component mixtures.
