摘要:
A microfluidic device with integrated electrodes for the electrochemically-modulated extraction of ions across immiscible aqueous-organic liquid-liquid interfaces is presented. Using a Y-shaped microfluidic channel with in situ electrodes and co-flowing aqueous and organic immiscible electrolyte solutions, the manipulation of the applied interfacial potential enabled the extraction of ions from the aqueous phase into the organic phase. Data for the extraction of tetraethylammonium cations from aqueous electrolyte into 1,2-dichloroethane electrolyte are presented. The device demonstrates the benefits of combination of microfluidics and liquid-liquid electrochemistry. (C) 2007 Elsevier B.V. All rights reserved.
