Abstract:Surfactants are amphiphilic molecules that adsorb to interfaces and affect the interfacial tension. Surfactants in seawater can impact gas-exchange, surface properties, and the composition and fate of sea spray aerosol. The accurate quantification of surfactants and their classes is crucial to constraining the effect of surfactants in seawater and their role in air−sea exchanges. Here, we evaluate and optimize a solid phase extraction (SPE) method paired with colorimetry and UV−vis spectroscopy to quantify the… Show more
