Evidence of Water in Organic Phase. The concentration of water in the organic solvent which is in contact with the aqueous phase was estimated by Karl Fisher water content analysis. The following protocol were used for analyzing various organic solvents: Each organic solvent (such as Decane, Dodecane, Diesel, Xylenes and Toluene) were individually purified by passing it thrice through activated alumina columns. These purified solvents were initially analyzed for estimating the concentration of water in it by Karl Fisher analyzer (Mettler Toledo, automatic titrator, Robertlit Laboratories, USA). At this stage, the studies on equilibrium water content in each of the organic solvent which are in contact with aqueous phase were systematically conducted (as experimental system listed in Table ) after storing it for 24 h in isolation chambers to prevent cross contamination. In-order to estimate the water concentration in the organic phase after equilibration with the aqueous solution, a thoroughly cleaned conical flask (50 mL) was initially filled with 20 mL of aqueous phase (0.6 M salt water) in the presence (50 ppm of DDA and 50 ppm of Brij-35) and absence of surfactants (with and without addition of 20 ppm of PAM), following which, 20 mL of purified organic solvent (With and Without 18 ppm of PTBS pre-dissolved in it) was gently deposited over the aqueous phase using a Teflon tube (Dia = 1.5 mm). This setup was carefully made on a vibration isolation table. At this stage, the Teflon tube which is immersed in the organic phase whose other end is suspended freely in the atmosphere (with closed valve) was carefully siphoned to collect the organic solvent at the end of 24 h. All the above collected samples were tested using a standard Karl Fisher (KF) moisture/water content analysis technique (results tabulated in Table ).
