摘要： In removal of sulfate groups and chlorate groups from brine used for electrolysis, concentrated brine used in an electrolysis process or dilute brine whose concentration is decreased by electrolysis is fed to an anode chamber divided by a cation exchange membrane in a brine treating electrolyzer, where the concentrated or dilute brine is electrolyzed to recover chloride ions therein. The concentrated brine is electrolyzed at a rate of decomposition of salt higher than that in the ion exchange membrane electrolysis process of brine. Thereafter, the concentrated or dilute brine is discharged out of the electrolysis process.

摘要： CMPO is safely, reliably and rapidly decomposed under mild conditions. A CMPO-containing substance is emulsified in an electrolyte comprising an oxidation promoter (silver ion) by an emulsifier in an emulsifying tank, this electrolyte comprising the CMPO-containing substance is supplied to an anode chamber, and an electrolytic oxidation reaction is performed by passing an electric current. By emulsifying the CMPO-containing substance, the surface area of CMPO in contact with electrolyte is increased, and electrolytic decomposition is thereby promoted. As sufficient CMPO decomposition is not obtained by passing the emulsion only once through an electrolysis tank 1, a batch oxidation method is employed wherein an anolyte is recirculated by a recirculating pump 3a through the anode chamber, a constant temperature bath 7a and an emulsifying tank 6, so that electrolysis is performed with the CMPO-containing substance permanently emulsified in the electrolyte. To maintain a catholyte in a cathode chamber at the same temperature as the anolyte, the catholyte is recirculated by a recirculating pump 3b between the cathode chamber and a constant temperature bath 7b. The current supplied to an anode 4 and cathode 5 in the electrolysis tank 1 is controlled by a rectifier 8.

摘要： A method for removing sulfate ions from an aqueous solution of an alkali metal chloride is disclosed, in which the aqueous solution of the alkali metal chloride containing sulfate ions and zirconium hydrous oxide are brought into contact with each other in a slurry form under acidic conditions to thereby cause the sulfate ions to be adsorbed to the zirconium hydrous oxide by an ion exchange reaction, the zirconium hydrous oxide adsorbing sulfate ions is separated from the aqueous solution and then dispersed in another aqueous liquid to thereby cause it to react with an alkali so as to cause sulfate ions to be desorbed into the aqueous liquid. According to this method, adsorption and desorption take place rapidly and efficiently.
