Calcium fluoride is a slightly soluble compound commonly extracted from ores via flotation at elevated pH, where surfactant molecules bind with hydroxylated surface sites. The addition of F-(aq) suppresses surfactant adsorption by replacing these sites. In this paper, we look at the effects of aqueous Cl-, Br-, F-, and SO4(2-) on the water structure at the(More)
Vibrational sum-frequency spectroscopy is a powerful tool for the study of interfaces, but its application has hitherto mainly been limited to static structure. This contribution demonstrates how the considerably improved stability of state-of-the-art lasers and parametric generators can be exploited to study the evolution of interfacial structure(More)
The adsorption, desorption, and equilibrium monomer exchange processes of sodium dodecanoate at the fluorite(CaF 2)-water interface have been studied. For the first time, we use in situ vibrational sum-frequency spectroscopy (VSFS) to gain insights into the mechanism and kinetics of monolayer self-assembly at the mineral-water interface. By exploiting the(More)
Self-assembly of surface-active agents at solid–liquid interfaces is critical for many processes in nature and technology, including the stability of suspension, detergency, wetting and mineral separation. [1] Historically, a detailed understanding of nano-meter-scale layers has emerged. However, surprisingly little is known about their dynamics—the key to(More)
