Zinc–Carboxylate Binding in Mixed Octadecanoic Acid and Octadecanol Monolayers on Proxy Seawater Solution Surfaces

Abstract: Organic coatings on sea spray aerosol are largely comprised of fatty acids in addition to a vast array of other organic molecules including fatty alcohols. The seawater from which sea spray aerosol originates contains metal ions that interact with the organic coating at the air–seawater interface, resulting in transport of these metals into the atmosphere. Metal binding within single-substance monolayers on aqueous solutions has been previously studied. However, such binding events within mixed monolayers, esp… Show more

“…Baumler and Allen reviewed vibrational spectroscopy in 2018. 89 Since then, Allen and coworkers, [90][91][92] Grassian and coworkers, 93 and Du and coworkers [94][95][96][97][98][99][100] have published many new studies on the use of infrared reection absorption spectroscopy (IRRAS) to probe model surfactant systems relevant to sea spray aerosol. Allen and coworkers have also continued to explore the surfaces of model sea spray systems with vibrational sum frequency generation (SFG) spectroscopy.…”

“…Sea spray aerosols (SSAs) present highly dynamic microenvironments in which their interfacial properties are strongly driven by chemical and physical interactions such as carboxylate−metal binding, 1,2 acid−base equilibrium, 3−5 and ion hydration. 6−8 Each of these parameters unlocks important thermodynamic inputs for global climate models, which provide better insights into atmospheric phenomena like ice nucleation and cold cloud formation.…”

“…Carboxylate−metal interactions under oceanic and atmospheric conditions have been well documented in the literature using various spectroscopic techniques. [1][2][3]23 Exposure to high concentrations of NaCl drives the interfacial equilibrium for certain semisoluble acids, demonstrating a need to expand upon Na + studies, such as their thermodynamically driven interactions, at SSA interfaces. 3 However, the thermodynamic properties of these carboxylate−metal interactions persist as nontrivial measurements.…”
