摘要： An electrochemical cell includes a housing having an inlet, an outlet, and a central axis and an anode-cathode pair disposed concentrically within the housing about the central axis and defining an active area between an anode and a cathode of the anode-cathode pair. An active surface area of at least one of the anode and the cathode has a surface area greater than a surface area of an internal surface of the housing. The anode-cathode pair is configured and arranged to direct all fluid passing through the electrochemical cell axially through the active area.

摘要： Methods are disclosed for removing alkali metal iodide from concentrated aqueous alkali metal chloride solutions using ion retardation resins. The methods are suitable for solutions comprising substantially more than 1 ppm iodide and greater than 100 g/l alkali metal chloride and can remove the iodide to levels below 1 ppm. To effect removal, the pH of the solution is adjusted to be less than about 10 and is then flowed through a separation bed comprising the resin in a series of loading and elution cycles. The method is particularly useful for removing iodide impurity from the concentrated feed brine used in chloralkali electrolysis.

摘要： [Problem] To provide an electrolysis method, whereby it becomes possible to produce oxidized water for sterilization/disinfection use in a neutral pH range by anodically oxidizing raw water, e.g., tap water, effectively utilizing halogen ions, e.g., chlorine ions, contained in the raw water. [Solution] A method for producing oxidized water for sterilization use which contains chlorine dioxide, said method comprising: electrolyzing tap water containing chlorine ions using a three-chamber-type electrolysis vessel, then trapping the chlorine ions dissolved in the tap water, and then electrolytically oxidizing the trapped chlorine ions on an anode electrode. The three-chamber-type electrolysis vessel is composed of an anode chamber, a cathode chamber and an intermediate chamber which is located between the anode chamber and the cathode chamber and is formed by providing partitioning membranes between the anode chamber and the cathode chamber. In the three-chamber-type electrolysis vessel, a partitioning membrane that isolates the anode chamber from the intermediate chamber is composed of a fluorine-containing cation exchange membrane and an anion exchange membrane, wherein a porous anode electrode is adhered onto the fluorine-containing cation exchange membrane in the partitioning membrane; a partitioning membrane that isolates the cathode chamber from the intermediate chamber is composed of a cation exchange membrane or an anion exchange membrane, wherein a porous cathode electrode is adhered onto the partitioning membrane; and an anion exchange resin is filled in the intermediate chamber.
