| Abstract
| - The rectified diffusion growth of a single air bubble levitated in an acoustic field (frequency = 22.35 kHz)in water and in aqueous solutions containing surfactants (sodium dodecyl sulfate and sodium dodecylbenzenesulfonate) was investigated. As reported by Crum (J. Acoust. Soc. Am.1980, 68, 203), the presence of surfactantsat the bubble/liquid interface enhanced the growth rate of the bubble by rectified diffusion. It is suggested inthis paper that in addition to the effect of surfactants on the surface tension and interfacial resistance to masstransfer, the effect of surface rheological properties may also contribute to the cause of the enhancementobserved in the bubble growth rate.
