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



We present an analytical approach for the detection of perfluorooctane sulfonate (PFOS) by ion transfer stripping voltammetry at an array of micro-interfaces between two immiscible electrolyte solutions. With this approach, picomolar concentrations are detected and environmental matrix effects are evaluated.
