Drop weight technique for the measurement of dynamic surface tension

Dynamic Interfacial Tensions of Aqueous Triton X-100 Solutions in Contact with Air, Cyclohexane,n-Heptane, andn-Hexadecane

“…From where the detected drop volume is affected by the so-called the three known quantities bulk phase concentration (c 0 ), hydrodynamic effect (11). This effect simulates higher val-concentration dependent adsorption (G c ) of the surfactant ues of the interfacial tension due to the detection of higher and slope of the curve in a g vs 1/ t ads plot, it is possible drop volumes and has to be corrected mathematically via to compute effective diffusion coefficients for the transport the following Eq.…”

Effect of micellar life‐time on the bubble dynamics in sodium dodecyl sulfate solutions

“…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.…”

Dynamics of drops — Formation, growth, oscillation, detachment, and coalescence

“…[80,81]). However, this function of separation time was later shown by Miller et al [82] to also include various parameters that might affect the hydrodynamic effects of separation, such as surface tension, density difference, and capillary size.…”
