Abstract
A simple and rapid method for the determination of the size distribution of gas bubbles in aqueous media is described which is, in principle, analogous to the size analysis of solid particles in a liquid by sedimentation. The procedure involves the measurement of the liquid column height as a function of time that elapses after the bubbling of gas has been discontinued. A pressure transducer, placed at a fixed position below the meniscus of the liquid, is used in these experiments. The size distribution of argon bubbles (0.1–1.5 mm in diameter) in aqueous solution of sodium hexadecyl sulfate (1 × 10−6 and 1 × 10−5 mole dm−3) was evaluated and the results compared with those obtained by the photographic method.
