Abstract
Abstract An electrolytic continuous method for simultaneously removing electrolytes from aqueous solution and concentrating the electrolytes produced therefrom which comprises subjecting an aqueous electrolyte solution to contact with an inorganic oxide gel under the influence of an electrical field, allowing the electrolyte to be sorbed by the gel until a point of saturation is achieved, whereby the electrolyte is exuded from said gel and then recovering the resultant electrolyte exudate from said gel. Conveniently, the apparatus comprises at least one electrolyte concentrating unit comprising an inorganic oxide gel core encased within an open module having a bottom wall and a pair of parallel opposing sides and opposing end walls and whose opposing sides further comprise a cation-permeable membrane and an anionpermeable membrane, respectively, and a source of an applied elecctrical field.
