Adsolubilization

WithJohn H. O’Haver, Lance L. Lobban, Jeffrey H. Harwell, Edgar A. O’Rear

Surfactants adsorbed at the solid/liquid interface can form aggregates that are much like micelles. These micelles can be used to solubilize organic 278molecules in the same manner that micelles are used. This phenomenon, called adsolubilization, has not been studied extensively and the first new technologies based on it are just beginning to emerge. The initial research on adsolubilization indicates that at high adsorption densities admicelles have adsolubilization capacities similar to micelles but with greater selectivity than micelles, probably because of the greater packing density which can be obtained in admicelles. At lower adsorption densities the capacity of admicelles may be many times the capacity of micelles for amphiphilic molecules.
