| Abstract: | The dynamic behavior of water-in-oil microemulsions (w/o), stabilized by sodium bis (2-ethyl-hexyl) sulphosuccinate (AOT), has been studied by means of stop flow method using spectroscopic detection. Kinetic model based on the ferroferric reaction was developed. Interdroplet exchange rate constant, k ex , associated with the exchange of materials upon collisions between droplets in w/o microemulsions system has been determined. k ex increases with increase in the chain length of linear alkanes and decreases with the water to surfactant molar concentration ratio (w 0 = H 2 O]/AOT]) and decreases in presence of viscosity modifier. |
