Abstract: An electrodeionization apparatus in which enough electric current flows even when the voltage applied between the electrodes is low, thereby sufficiently performing deionization is provided. A single first cation exchange membrane 3, a single anion exchange membrane 4, a single second cation exchange membrane 3′ are arranged between a cathode 1 and an anode 2 so that a concentration-cathode compartment 5, a desalting compartment 7, a concentrating compartment 10, and an anode compartment 6 are formed, in this order, between the cathode 1 and the anode 2. The concentration-cathode compartment 5 and the anode compartment 6 are filled with a cation exchange resin 8, respectively. The desalting compartment 7 is filled with a mixture of the cation exchange resin 8 and an anion exchange resin 9. Fed into the anode compartment 6 is raw water or deionized water. Water from the anode compartment is sent to the concentrating compartment 10 and the concentration-cathode compartment 5 sequentially.

Abstract: The invention provides a method and processing system for removing both anionic and cationic technetium complexes from an aqueous solution by adjusting the pH of the solution to greater than approximately 2, and directing the solution into an integrated resin and electrochemical plating device. The integrated resin and plating device has a resin bed or resin membrane in which is disposed one or more cathodes, and one or more anodes. A potential generator produces at least a 1 volt potential between the cathodes and the anodes. As the solution passes through the resin, the technetium complexes are adsorbed onto it. When a sufficient concentration of technetium complexes is adsorbed, the plating process can atlernatively be driven to plate out the technetium onto the cathodes, or to collect various species in system anolytes/catholytes.

Abstract: An electrodeionization apparatus is provided for removing ions from liquids. The apparatus is particularly well-adapted for the removal of large, heavily hydrated, highly charged or weakly ionized molecules or complexes from feed water. Such removal is achieved by substituting, in at least one section of the apparatus, ion exchange membranes and/or resins having lower crosslinking and/or lower selectivity, for the ion exchange membranes commonly used in electrodeionization systems. Methods for reducing the electrical resistance across the membrane also are provided.

Abstract: Applying a desorbing wave energy to a soil matrix can effect desorption of ionic species which are associated with the matrix. This method is especially applicable to decontamination of soils to which metals and/or radioactive isotopes are adsorbed. The desorbing energy may be microwave energy, sonic or ultrasonic energy, etc., or combinations thereof. An electromagnetic potential also can be applied to the matrix to enhance desorption and or migration of the species. An electrolyte also may be added to the matrix to enhance desorption and or migration of the species.
