.... The optimum initial pH was between 6 and 6.5 for salinity between 0 to 15 wt% NaCl. However, for higher salinity environment, 15 to 25 wt% NaCl, foam stability at low pH shows drastic improvement over its counterpart at lower salinities. At these high salinities, the optimal surfactant concentration was 0.50...
