Coalescence of Bubble Pairs in Surfactant Solutions
This paper is concerned with the coalescence behaviour of two bubbles in dilute solutions of cetyltrimethylammonium bromide, methyl isobutyl carbonil and triton x-100. Two bubbles were produced at the tips of adjacent capillaries and the time elapsed between the first contact of the bubbles and film rupture was determined by means of a high speed camera. It was found that the amount of surfactant required to stabilise the bubbles increased in order of CTAB>TX-100>MIBC.The probability of coalescence decreased sharply with increasing surfactant concentration in CTAB and TX-100 solutions while with MIBC each bubble pairs resulted in coalescence, giving hundred percent coalescence probability.
