Abstract:
An apparatus for generating an acid or base comprising:(a) an ion source reservoir containing a source of either anions or cations, (b) an acid or base generation chamber having inlet and outlet ports, the volume of said ion source reservoir being at least about 5 times the volume of said acid or base generation chamber, (c) a charged first barrier disposed between said ion source reservoir and said acid or base generation chamber, said barrier substantially preventing liquid flow while providing an ion transport bridge for only ions of one charge, positive or negative, (d) a first electrode in electrical communication with said ion source reservoir, (e) a second electrode in electrical communication with said first acid or base generation chamber, and (f) an aqueous liquid source in fluid communication with said acid or base generation chamber inlet port.
