Abstract

Objectives: To select a specific concentration of surfactant, that could optimize Ultralow Interfacial tension between oil and Water. Formation of micro emulsion through Emulsion Test. Methodology: This work has been done through conductivity measurement of eight different surfactant concentrations to determine stable Critical Micelle Concentration (CMC). This concentration has been tested with different concentrations of electrolyte and alkali for middle layer micro emulsion. Results and Observations: Sodium Dodecyle Sulphate has been chosen for conductivity test. Through conductivity test CMC has been determined at 500ppm concentration. It has been tested with different concentrations of electrolyte and alkali for middle layer micro emulsion. Third layer have been appeared at NaCl 1.0 wt% and Alakli 0.5 wt%. At this particular concentration IFT between Oil and Water have been reduced.
