title: Simultaneous Preconcentration and Desalting of Organic Solutes in Aqueous Solutions by Bubble Bursting.
abstract: Significant efforts are being made to develop more practical and versatile approaches for the preconcentration and purification of complex chemical samples. Inspired by the naturally occurring enrichment of organic compounds in sea aerosols, in this study we demonstrate the potential of induced bubble bursting as an approach for the preconcentration of organic solutes in various aqueous solutions. Apart from the preconcentration of organics, notable decrease in the concentration of metal salt components was discovered for the first time. On the basis of a series of model experiments, the phenomenon has been attributed to intermolecular competition at the surface interface of rising bubbles. Overall, our results indicate the high versatility and simplicity of the bubble bursting approach for the simultaneous preconcentration and desalting of organic solutes in aqueous solutions for mass spectrometry, chromatography, optical detection, and other fields of analysis.
