Surfactant enhanced mobilisation of non-aqueous phase liquids
… through Ottawa sand spiked with light white mineral oil. At the higher flow rate, the surfactant solutions yielded N T values greater than the critical N T , promoting greater NAPL recovery as IFT dropped. While NAPL removal at the lower flow rate should not be enhanced because the critical N …

Characterization of surfactant adsorption at a liquid-liquid interface by drop volume tensiometry
… as the removal of hydrophobic contaminants from soils through surfactant-enhanced washing or flushing processes. Dynamic interfacial tension measurements can be useful in describing the adsorption behavior of surfactants at liquid-liquid interfaces. In this work, selected surfactants are tested at …
