Abstract:<\/h4>\n
This study reports a novel approach for separation of charged species using anion\u2010exchange hydrogel (AEH) and cation\u2010exchange hydrogel (CEH) in a microfluidic device. The capillary line pinning technique, which is applied in this study, enables in situ fabrication of alternating AEH and CEH that are placed in confined compartments. Adjacent enriched and depleted streams are obtained in continuous flow when a potential difference is applied over the hydrogel stack. The desalination performance of the microchip is demonstrated at different salt concentrations (0.01 \u00d7 10 \u22123 \u20131\u00d7 10 \u22123 m sodium chloride), potentials (10\u2013100 V), current densities (12\u201328 A m \u22122 ), and liquid flow rates (0\u20135 \u00b5L min \u22121 ). It is shown that the microchip is able to remove \u224875% of the salt initially present in the depleted outlet streams at inlet stream concentrations of 1 \u00d7 10 \u22123 m sodium chloride. Besides desalination, the microchip allows study of ion transport in the ion\u2010selective hydrogels to elucidate the interplay of transport phenomena at the electrolyte\u2013hydrogel interface during the desalination process.<\/p>\n","protected":false},"excerpt":{"rendered":"
