| Popis: | A new spray column-type extractor, in which the gas (air) was injected from the inside tube (0.2φ I.D.) into a liquid droplet (toluene or toluene+24.5wt% CCl4) flowing from the annular space of the double tube (outside tube: 0.65φ, 1.10φ and 2.80φ I.D.), liquid droplets combined with gas bubbles ( = two-phase droplets) were formed at the tip of a nozzle, and the solute (acetic acid) in droplets was extracted with water, is proposed. The density of dispersed-phase liquid, the volume ratio of gas to oil in the two-phase droplet and the nozzle diameter were varied, and the results showed that the increase of the volume ratio of gas to oil in the two-phase droplet led to high efficiency of the extraction. |
