The gas phase in liquid imsaturated porous media can contain a wide variety of important chemical constituents. For example, the amoimt of carbon dioxide gas (CO2) in the soil can affect the chemistry of aqueous solutions, and the tendency for aerobic and anaerobic conditions is reflected by the existence and amoimt of oxygen gas (O2). 

A range of fluorinated anionic surfactants, which are structural relatives of Aerosol-OT, were synthesized and characterized, with the aim of investigating the effects of chemistry on the structure and stability of water-in-carbon dioxide microemulsions. The dilute aqueous phase behavior was studied to check for chemical purity and fuUy characterize the compounds. Once appropriate measures were taken to achieve sufficient purity, the surface excesses measured by both tensiometry and neutron reflection measurements agreed well, and the surface tensions were consistent with a prefactor of 2 in the Gibbs equation.
