Aqueous pH alters the protein charge property and affects the extraction efficiency. Haemoglobin (Mw 64,500, pi 6.8) is a difficult protein in terms of being able to completely extract it into reverse micelles. The representative anionic surfactant, di-2-ethylhexyl sulfosuccinate (AOT), cannot extract it, and gives rise to an interfacial precipitate. In contrast, we succeeded in the complete extraction of haemoglobin using synthetic anionic surfactants, dioleyl phosphoric acid (DOLPA), as seen in...

There have been fewer reports on the particle size dependence of catalysis by platinum-catalyzed redox reactions. A report by Sharma et al. [21] showed that platinum colloidal nanoparticles do not demonstrate the same dependence on particle size as gold nanoparticles do for the reduction of hexacyanoferrate (III) by thiosulfate [19]. Platinum nanoparticles protected by sodium di(2-ethylhexyl) sulfosuccinate (synthesized by a reverse micelle technique) exhibit an optimum size ( 38 nm) for the reduction of ferricyanide by thiosulfate (Fig. 18.2). The reason for an optimum particle size is not fully understood however, they proposed the following explanation a shift in the Fermi level occurs as the diameter is increased. 

The spectroscopic probe pyridine-N-oxide was used to characterize polar microdomains in reverse micelles in supercritical ethane from 50 to 300 bar. For both anionic and nonionic surfactants, the polarities of these microdomains were adjusted continuously over a wide range using modest pressure changes. The solubilization of water in the micelles increases significantly with the addition of the cosolvent octane or the co-surfactant octanol. Quantitative solubilities are reported for the first time for hydrophiles in reverse micelles in supercritical fluids. The amino acid tryptophan has been solubilized in ethane at the 0.1 wt.% level with the use of an anionic surfactant, sodium di-2-ethylhexyl sulfosuccinate (AOT). The existence of polar microdomains in aggregates in supercritical fluids at relatively low pressures, along with the adjustability of these domains with pressure, presents new possibilities for separation and reaction processes involving hydrophilic substances. 

Effect of Temperature For ionic surfactants an increase in temperature generally results in an increase in the extent of solubilization for both polar and nonpolar solubilizates, possibly because increased thermal agitation increases the space available for solubilization in the micelle. Thus, the solubilization of cyclohexane in an aqueous solution of sodium di(2-ethylhexyl) sulfosuccinate above 50°C increases with increase in the temperature (Kunieda and Shinoda, 1979). 

These effects on the solubilization of water are in agreement with the prediction of Mitchell and Ninham that bringing the > 1 value of the ratio Vh /1c< o (Chapter 3, Section II) closer to 1 should increase the solubilization of water in inverted micelles. This is also consistent with increases in the solubilization of water observed upon the addition of benzene or nitrobenzene to solutions of sodium di(2-ethylhexyl)sulfosuccinate in isooctane (Maitra, 1983). The effects were explained as caused by desolvation of the surfactant by the additives, with consequent decrease in the value of Vh-...

One can conceive that an anionic surfactant like sodium-di-2-ethylhexyl-sulfosuccinate (NaAOT) or sodium dodecyl sulfate (SDS) can be called so in working terms when the positively charged counterion, sodium, gets detached from the molecule and is released into the solvent in which the surfactant is dissolved. The same is true for the surfactant cetyltrimethylammonium bromide (CTAB) in which case the negatively charged bromide ion should be detached from the molecule so that the latter can become cationic . 

Anionic surfactants are typically alkali metal salts of long-chain carboxylic or sulfonic acids, for example sodium di-2-ethylhexyl sulfosuccinate (Aerosol OT).
