A system and a method are provided for making hypochlorous acid using saltwater with bicarbonate compound. The system includes an electrolytic cell, a quantity of saltwater solution, and a quantity of bicarbonate compound. The quantity of saltwater solution is poured into the electrolytic cell and then undergoes an electrolytic process. As a result of the quantity of saltwater solution going through the electrolytic process, a hypochlorous acid solution is yielded. In order to ensure a pure hypochlorous acid solution is formed, the quantity of bicarbonate compound can be added into the electrolytic cell along with the quantity of saltwater solution before the electrolytic process or the quantity of bicarbonate compound can be added into the hypochlorous acid solution after the hypochlorous acid solution is yielded. This process adjusts the pH level of the hypochlorous acid solution, and thus, produces a purer hypochlorous acid solution.

The present invention relates to a manufacturing apparatus and method for customizing a H.sub.2/CO synthetic gas in a desired ratio by producing a synthetic gas in which H.sub.2 and CO are mixed through hydrolysis of both carbon dioxide and a nitrogen compound with low power. In a low-power electrochemical apparatus for producing a synthetic gas according to the present invention, by performing the reduction of the carbon dioxide at the cathode and the oxidation of the nitrogen compound at the anode at the same time, carbon dioxide conversion efficiency may be improved 30% or more compared to the conventional carbon dioxide conversion system, and a synthetic gas with a desired H.sub.2/CO ratio may be produced by controlling the H.sub.2/CO ratio of the produced synthetic gas, and by reducing a driving voltage, the corrosion problem of electrode materials may be inhibited and the durability of electrodes may be increased.

An electrochemical electrode according to the present invention may prevent agglomeration and desorption of a catalyst even when a catalyst in a particle form is used, because a protective layer containing hydrogel is used, such that stability may be secured, thereby implementing an electrode having a long duration.

Disclosed herein are methods and systems that relate to oxidizing a metal ion of a metal oxyanion or a non-metal ion of a non-metal oxyanion from a lower oxidation state to a higher oxidation state at an anode and generate hydrogen gas at the cathode. The metal oxyanion with the metal ion in the higher oxidation state or the non-metal oxyanion with the non-metal ion in the higher oxidation state may be then subjected to a thermal reaction or a second electrochemical reaction, to form oxygen gas as well as to regenerate the metal oxyanion with the metal ion in the lower oxidation state or the non-metal oxyanion with the non-metal ion in the lower oxidation state, respectively.

A method of preparing metal hydroxides from industrial wastes or alkaline rocks is provided. The method comprise subjecting a mixture comprising a solvent and a solid substrate to a stimulus in order to leach a metal cation from the solid substrate into the solvent, thereby forming a solution comprising the metal cation in the solvent; and contacting the solution of comprising the metal cation with a cathode, thereby electrolytically precipitating the metal hydroxide from the solution. The stimulus may be chemical, mechanical, or both.

A method is described herein that produces UN from UF.sub.6 in at most two steps comprising UF.sub.6.fwdarw.intermediate.fwdarw.UN. The principle of the reaction is that in a first step, UF.sub.6 would be reduced to U.sub.xN.sub.y, where x may be an integer selected from 1 and 3, and y is an integer selected from 1 and 2. Reduction occurs at or near the surface of a gaseous membrane electrode where it is also in contact with a nitrogen bearing salt. In a second step, U.sub.xN.sub.y decomposes to UN and N.sub.2 gas, either in the same reactor as the first step or after removal to a separate unit for further processing.

The present disclosure broadly relates to a process for preparing aqueous solutions of vanadium sulfates or aqueous solutions of transition metal sulfates. More specifically, but not exclusively, the present disclosure relates to a direct electrochemical process in which a suspension, obtained by slurrying transition metals oxides such as oxides of vanadium, oxides of iron, oxides of cobalt, oxides of nickel, oxides of chromium, oxides of manganese, oxides of titanium, oxides of cerium, oxides of praseodymium, oxides of europium, oxides of terbium, oxides of uranium, oxides of plutonium, or their mixtures thereof with sulfuric acid as carrier fluid, is reduced electrochemically inside the cathode compartment of an electrolyzer to produce an aqueous solution of vanadium sulfates or of transition metal sulfates. Simultaneously, oxidizing co-products are produced in the anode compartment.
