“…The dynamic surface tension can be measured by the drop weight (Jho et al, 1983), oscillating jet (Thomas et al, 1975), capillary wave (Austin et al, 1967), and maximum bubble pressure methods (Mysels, 1989). Rosen et al (1988) showed that the dynamic surface tension of surfactant solutions decreases more rapidly as the concentration of surfactant or the temperature increases.…”
