摘要： A heterocyclic compound having a structure in which a benzene ring and a nitrogen-containing heterocycle are condensed is added to a sulfuric acid solution that contains a persulfuric acid component such as peroxomonosulfuric acid, peroxomonosulfate, peroxodisulfuric acid, or peroxodisulfate as an oxidant and in which impurities that promote the reduction in the oxidant concentration are present. Here, the heterocyclic compound having a structure in which a benzene ring and a nitrogen-containing heterocycle are condensed is preferably a benzotriazole-based compound. The impurities that promote a reduction in the oxidant concentration are suitably one or more selected from copper ions, iron ions, nitrate ions, and nitrite ions. The method of the present invention of inhibiting a reduction in the oxidant concentration in a sulfuric acid solution containing a persulfuric acid component can inhibit the reduction in the oxidant concentration to a minimum even when impurities that cause a reduction in the oxidant concentration are mixed.

摘要： Compositions and methods for oxidizing organic contaminants while sequestering inhibitory forms of carbon. An oxidant capable of producing free radicals oxidizes organic contaminants. A metal oxide, metal hydroxide, or metal peroxide generates a soluble hydroxide concentration of about 1×10−4 M or greater to convert carbonic acid, bicarbonate ion, methane, elemental carbon, and other organic forms of carbon to carbonate ion. A metal having a carbonate with a lower solubility product constant than its hydroxide precipitates the carbonate ion as a metal carbonate, thereby eliminating soluble carbonate as a radical scavenger. Compositions and methods that additionally minimize metal solubilization and sequester solubilized metals are also disclosed.

摘要： A method and composition for reducing chemical oxygen demand is presented. The composition includes a persulfate donor, a transition metal catalyst in contact with the persulfate donor, and a cationic electrolyte. When the composition is contacted by water, the transition metal catalyst reacts with persulfate and reduces the persulfate concentration in the water. The composition allows the use of persulfate, which is known to cause irritation to users of aquatic facilities (e.g., pools, spas) that come in contact with it. As the persulfate concentration is reduced rapidly in the water by the catalyzed reaction, the persulfate-containing product may be applied while the aquatic facilities are being used. A free halogen donor may be incorporated into the composition. The composition may be in the form of powder, granules (coated or uncoated), or agglomerate. The cationic electrolyte facilitates the removal of the catalyst from the water.
