本文着重研究了表面活性剂对气泡尺寸的影响。本文研究了十二烷基硫酸钠/水体系在不同表观气速（0.13，0.26和0.5cm/s）下气泡尺寸的变化。另一方面，测定了不同十二烷基硫酸钠表面活性剂浓度下的气泡直径。水中的表面活性剂浓度为0.05、0.02和0.1体积%。自来水和具有表面活性剂（阴离子、非离子和两性离子）的水溶液用作液相。在此阶段中的气泡尺寸在Cs=0.05%vol和μ g = 0.13cm/s下确定。气泡在高度为1.2 m的有机玻璃制成的小型鼓泡塔中产生。高速摄影技术被用来测量气泡尺寸。实验结果表明，十二烷基硫酸钠/水体系的气泡直径大于其它体系。在十二烷基硫酸钠溶液中，Sauter平均气泡直径（位置A和D）随着表观气速的增加而减小。
This paper focuses on the effect of surfactants on the bubble size. Bubble size in Sodium dodecyl sulfate / water system were investigated at various superficial gas velocities (0.13, 0.26 and 0.5 cm/s). On the other hands, Bubble diameter was determined for different values of Sodium dodecyl sulfate surfactant concentration. Surfactant concentration in water were 0.05, 0.02 and 0.1 vol.%. Tap water and aqueous solutions with surfactants (anionic, non-ionic and zwitterionic) are used as liquid phases. The bubbles size in this phase is determined at Cs=0.05%vol and u g =0.13 cm/s. The bubbles are generated into a small-scale bubble column making of Plexiglas with height of 1.2 m. High speed photography techniques are used to measure the bubble size. The experimental results were shown that bubble diameter in Sodium dodecyl sulfate /water system is larger than other systems. In solution of Sodium dodecyl sulfate, Sauter mean bubble diameter (Location A and D) decreases when superficial gas velocity increased.
