Properties of aqueous foams stabilized by dodecyltrimethylammonium bromide

Foamability, foam stability and the liquid volume of aqueous foams stabilized by dodecyltrimethylammonium bromide (C12TAB) are studied. The foams are generated with a sparging method at different gas flow rates and surfactant concentrations. It is found that at concentrations c⩾cmcc⩾cmc drainage dominates foam destruction while at c

Graphical abstractA commercially available sparging foaming technique (FoamScan) is applied in order to study the foaming properties of dodecyltrimethylammonium bromide (C12TAB) solutions. Various sparging flow rates and surfactant concentrations were investigated.Figure optionsDownload full-size imageDownload as PowerPoint slide
