Cloud Point Extraction

Extraction systems based on nonionic surfactants have been described as an alternative to the standard polymer polymer or polymer salt systems. Phase-forming surfactants are, for example, the nonionic polyoxyethylene-type detergents. This kind of aqueous two-phase system (ATPS) is simply induced by a switch in the temperature on the basis of the temperature-dependent reversible hydration dehydration of the polar ethylene oxide headgroups. A single isotropic micellar phase separates into two...
