摘要: Abstract The influence of a surface-active substance upon the behaviour observed for gas–liquid interfacial area in bubble column has been studied employing two different techniques: chemical and photographic methods. Important differences between values have found, they assigned to phenomena existing this kind systems, especially Marangoni barrier effect. experimental results obtained work under operational conditions imply that method is greatly influenced by existence surface tension gradients, phenomenon produces high area.
