Summary:Bubble-based systems and methods to detect surfactants, such as perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) in aqueous solutions including water supplies are described. The systems and methods can utilize a surfactant preconcentration step to increase the sensitivity of the methods. Preconcentration can be based on aerosol formation and capture.
