Popis:	Experiments were conducted to study the gas-liquid mass transfer of a single bubble containing an ozone-oxygen gas mixture in liquids and liquid-solid fluidized beds. A spectrophotometric technique is developed for the measurement of the instantaneous mass transfer coefficient and the local concentration distribution around the bubble wake. The method employs an ultraviolet light source and optical fibers. Axial variations of the mass transfer rate are studied. An ozone and starchiodide complex reaction is employed to visualize the mass transfer phenomena.
