Simultaneous Preconcentration and Desalting of Organic Solutes in Aqueous Solutions by Bubble Bursting
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
