Bubble adhesion on hydrophobic surfaces in solutions of pure and technical grade ionic surfactants

Original language description

The attachment of bubbles onto a collecting surface plays a critical role in many industrial processes. Here, the bubble behaviour is crucially influenced by the presence of surface active agents, where the ionic surfactants are the most common agents. The ionic surfactants very often contain contaminants which, even in trace amounts, could unexpectedly influence the bubble adhesion. This work is focused on an experimental study of bubble adhesion onto the hydrophobic surface in solutions of two ionic surface-active agents (DTAB and SDS) of pure and technical grade purity. The diameters of the three-phase contact line together with bubble dynamic contact angles, dynamic surface tension and dynamic drop contact angles are measured. It was observed that the contaminants decrease the ability of bubbles to attach to solid surfaces when compared with the mono-surfactant solution. The influence of contaminants is crucial below the critical micelle concentration of the main surfactant and it may even happen that the capture of bubbles is avoided. ? 2017 Elsevier B.V.
