Determination of the critical micellar concentration of perfluorinated surfactants by cyclic voltammetry at liquid/liquid interfaces

Detection of perfluorooctane sulfonate by ion-transfer stripping voltammetry at an array of microinterfaces between two immiscible electrolyte solutions

“…Several target analytes has been detected by ion transfer electrochemistry at the ITIES. 25,26,27,28 with a millmetre-or centimetre-scale interface are limited in their analytical usefulness due to linear diffusion and mechanical instability of the interface. These limitations can be overcome by miniaturization of the ITIES to microscale (𝜇ITIES), 29,30,31 which enhances mass transport to the interface and improves the detection capabilities, while the mechanical stability can be improved by the use of a porous membrane to support the ITIES.…”

Detection of Perfluorooctane Sulfonate by Ion-Transfer Stripping Voltammetry at an Array of Microinterfaces Between Two Immiscible Electrolyte Solutions

“…Such behaviour has been reported for PFOS -60 and other PFAS. 25 Considering that the analyte transferred to the organic phase is solvated in DCE, the critical micelle concentration (CMC) will be different from that in water. However, although formation of PFAS reverse micelles in organic phases has been discussed, 61 no CMC values were reported.…”
