KINETICS OF CLEANING

The question arises as to whether the microemulsion phase retains the high transport rates for which supercritical fluids are well know.f lf Various spectroscopic studies that are described in the following section have been used to directly measure the transport properties in supercritical fluid or near-critical liquid microemulsions. 

Dynamic light scattering has been utilized to directly measure droplet diffusion coefficients in near-critical and supercritical fluids. Blitz et al.f and Fulton et measured the effect of pressure on 

The rate at which the microemulsion droplets exchange the contents of their aqueous cores is another important transport variable. Exchange kinetics have been measured using fluorescence techniques. Dynamic fluorescence quenching has also been used to study micelle size. f The technique is, however, more useful as a tool to explore the exchange kinetics between microemulsion droplets. The systems studied were AOT or didodecyldimethyl ammonium bromide and water in propane up to 100°C and
