Hydrogen peroxide and gluconic acid production
A hydrogen peroxide and gluconic acid production method and system is disclosed that can include receiving an aqueous solution having glucose, water, and glucose oxidase at a reaction chamber. Here, the reaction chamber facilitates an enzymatic reaction between a gas phase and a liquid phase of the aqueous solution, thereby yielding a first solution comprising hydrogen peroxide, gluconic acid, and the glucose oxidase. The method can further include receiving the first solution at a separation chamber, wherein the separation chamber is comprised of a semi-permeable membrane having a pre-defined molecular weight barrier for separating the glucose oxidase, thereby resulting in a combined hydrogen peroxide and gluconic acid solution. The method can further include at least partially converting the gluconic acid into a gluconate salt, and separating and concentrating the hydrogen peroxide from the gluconic acid or gluconate salt via vacuum flash evaporation and vacuum distillation.
METHOD FOR PRODUCING NEW ALLOTROPIC MODIFICATION OF OXYGEN, TETRAOXYGEN O4, AND DEVICE FOR ITS PRODUCTION.
Disclosed herein is a method and device for production of a new long-term storage-stable allotropic modification of oxygen, tetraoxygen O.sub.4, using a combination of known chemical reactions into one technological sequence, including chemical interaction of negative and positive oxidation state oxygen compounds.
The method involves production of dioxygen difluoride by oxidation of molecular oxygen with fluorine, followed by the reaction of dioxygen difluoride with alkali metal peroxide, forming tetraoxygen O.sub.4.
Tetraoxygen is stable in its liquid state up to a temperature of +40° C. and can be used for the oxidation of rocket fuel, long-term compact storage of oxygen, and many other purposes.

Devices, systems, and methods for sterilization, disinfection, sanitization and decontamination
A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.
Treatment of high peroxide waste streams
A method of reducing a concentration of hydrogen peroxide from wastewater includes diluting the wastewater with water having a lower concentration of hydrogen peroxide than the wastewater to produce a diluted wastewater, contacting the diluted wastewater with a dissolved iron compound at an acidic pH to form a partially treated wastewater having a lower concentration of hydrogen peroxide than the diluted wastewater, and precipitating iron solids from the partially treated wastewater by raising a pH of the partially treated wastewater to form a neutralized partially treated wastewater.
