摘要： A metal coil or an elastic cushion formed by winding the metal coil around a corrosion-resistant frame is sandwiched between an electrode and an electrode collector or a cell wall or is used as an electrode. The elasticity of the metal coil or the elastic cushion enables the easy handling and the uniform contact between the electrode and another electrolysis element. The metal coil or the elastic cushion can be also used as an elastic cathode. The elasticity of the elastic cathode also enables the easy handling of the electrode itself and the uniform contact between the ion exchange membrane and the current collector.

摘要： The invention provides an ion exchange membrane electrolyzer ensuring a satisfactory circulation of electrolyte, high electrolytic efficiency and great ridigity. An anode chamber partition in a flat sheet form is joined to a cathode chamber partition in a flat sheet form. An electrode retainer member in a sheet form is joined to at least one partition at a belt-like junction. A projecting strip with an electrode joined thereto is located between adjacent junctions. A space on an electrode surface side of the electrode retainer member defines a path through which a fluid goes up in the electrode chamber, and a space that spaces away from the space defines a path through which an electrolyte separated from a gas at a top portion of the electrode goes down.

摘要： In a brine treatment method of removing sulfate ions from sulfate-ion contained brine, sulfate-ion contained brine is brought into dispersive contact with granular ion exchange resin carrying zirconium hydrous oxide thereon in a fluid state under an acidic condition to thereby cause the sulfate ions to be adsorbed by the ion exchange resin and removed from the brine, then the granular ion exchange resin is washed with aqueous solution whose pH value is equal to or lower than a pH value in the adsorbing step, thereby removing chloride ions from the granular ion exchange resin, then in a fluid state, the granular ion exchange resin adsorbing the sulfate ions is brought into dispersive contact with aqueous solution of pH value higher than the pH value in the adsorbing step, thereby desorbing the adsorbed sulfate ions from the granular ion exchange resin, and then the granular ion exchange resin is washed with water.
