Abstract
A new method of measuring dynamic surface tension rising maximum bubbl e pressure in a stopped-flow regime is proposed and the theoretical ba sis elaborated. The new technique is carried out with aqueous solution s of dimethyl dodecyl phosphine oxide at very low concentrations. The results obtained are in excellent agreement with data from other metho ds and support a theory of diffusion-controlled adsorption kinetics. T he method can also be used to estimate the concentration of trace leve ls of surfactants in river water.
