Effect of surfactants on liquid-side mass transfer coefficients [PDF]
Chemical Engineering Science, 2005 In the present paper, the effect of liquid properties (surfactants) on bubble generation phenomenon, interfacial area and liquid side mass transfer coefficient was investigated. The measurements of surface tension (static and dynamic methods), of Critical Micelle Concentration (CMC) and of characteristic adsorption parameters such as the surface ...
