摘要： Aqueous alkali metal chloride solutions, typically destined for electrolysis for the production of chlorine and containing a contaminating amount of iodine values in other than the periodate state, are purified by oxidizing the iodine values therein to the periodate oxidation state of +7 and then separating such periodate values therefrom. The starting alkali metal chloride solutions may also contain contaminating amounts of ammonium values, which in turn are oxidized, preferably simultaneously, to molecular nitrogen and degassed therefrom.

摘要： In a method for producing sodium hypochlorite, brine solution is piped from the brine tank to a first inlet in a first electrolyzer cell of an electrolyzer assembly while simultaneously piping chilled water from a chiller having a temperature range from about 10° C. to about 25° C. to the first inlet so that the brine solution combines with the chilled water. The chilled brine solution is electrolyzed in the first electrolyzer cell. The hypochlorite and brine solution resulting from electrolysis occurring in the first cell is piped to a second inlet in a second electrolyzer cell in the electrolyzer assembly while simultaneously piping chilled water from the chiller having a temperature range from about 10° C. to about 25° C. to the second inlet so that the chilled water combines with the hypochlorite and brine solution. Each cell can have more than one inlet, preferably up to 6 inlets. The chilled hypochlorite and brine solution are electrolyzed in the second cell. The process is repeated until the hypochlorite and brine solution passes through all cells of the electrolyzer assembly.

摘要： An electrolytic cell producing sodium chlorate uses an electrode, specifically an anode, having a surface or coating or treatment of a mixed metal oxide having ruthenium oxide as an electrocatalyst, a precious metal of the platinum group or its oxide as a stability enhancer, antimony oxide as an oxygen suppressant and a titanium oxide binder. The electrocatalytic coating is about 21 mole percent ruthenium oxide, about 2 mole percent iridium oxide, about 4 mole percent antimony oxide and the balance is titanium oxide. The coating is characterized by high durability and low oxygen content in an off-gas.

摘要： A batch or continuous process for the removal by flocculation of silicon and heavy metal contamination from aqueous waste streams by the addition of an aluminum salt, particularly, aqueous streams recycled as electrolyte in the electrolytic production of alkali metal or alkaline earth metal chlorates. The process is particularly suited to the removal of heavy metals and silicon contamination in an electrolyte recycled to an electrolytic cell subsequent to the removal by crystallization of a chlorate salt. An aluminum salt, such as aluminum chloride, aluminum chlorohydrate, and polyaluminum chlorides including polyaluminum chloride sulfates is effective as a flocculating agent.

摘要： A chlorination system in which brine is converted to sodium hypochlorite by an electrolyser. Brine (1) fed to the electrolyser (3) is passed through a filter (2) which is capable of adsorbing bromine or hypobromous acid. Some of the sodium hypochlorite produced in an electrolyser (3) is fed back to a point in the brine feed upstream of the filter (2) such that any bromide in the brine is oxidized to bromine or hypobromous acid and therefore adsorbed by the filter (2).

摘要： Chlorine dioxide is produced at high conversion rates from aqueous sodium chlorite solution by electrochemical oxidation in an undivided electrochemical cell. The cell utilizes an anode of high surface area through which the aqueous sodium chlorite solution flows into an interelectrode gap between the anode and a cathode. Water or acidified water is fed into the interelectrode gap to function as catholyte and also to dilute the electrolyzed sodium chlorite solution to provide an aqueous solution of chlorine dioxide exiting from the electrochemical cell.
