Semiequilibrium dialysis

Rouse, J.D., Sabatini, D.A., Deeds, N.E., and Brown, RE. (1995). Micellar solubilization of unsaturated hydrocarbon concentrations as evaluated by semiequilibrium dialysis. Environ. Sci. Technol, 29,2484-2489. 

The extent of solubilization of a hydrophobic solute present in water into a micelle is determined by semiequilibrium dialysis (SED) techniques. This technique employs a dialysis cell (see Figure 4.3.1(a)), where the pore size of the dialysis membrane completely rejects the spherical micelle. However, the solute must be able to pass freely through the membrane. The surfactant monomer may also pass freely through the membrane. On addition of surfactant at a concentration of Csur mol/liter to the chamber on one side of the membrane to which C° mol/liter of solute species i has been added, binding of the solute to the micelles will occur if the surfactant concentration exceeds the CMC for the surfactant.
