Abstract: The present invention provides a device and methods of use thereof for desalting a solution. The methods, inter-alia, make use of a device comprising microchannels, which are linked to conduits, whereby induction of an electric field in the conduit results in the formation of a space charge layer within the microchannel. The space charge layer provides an energy barrier for salt ions and generates an ion depletion zone proximal to the linkage region between the microchannel and the conduit. The method thus enables the removal of salt ions from the region proximal to the conduit and their accumulation in a region distant from the conduit, within the microchannel.
