Abstract:In the previous work, Xu Jirun and Kelsall G H have derived a new formula for bubble electrophoretic mobility by taking the internal circulation, surface charge perturbation and interface tension gradient into account. A comparison of the theoretical formula with the experimental results was given and some new aspects of the bubble electrophoresis were discussed in the present paper. It was shown that the new formula can predict the experimental facts, such as the dependence of electrophoretic mobility on bubble size and on electrical field direction that can not be explained by classical electrophoretic theory.

 

Key words: bubble electrophoresis electrophoretic mobility bubble size electrical field
