"chlorine dioxide in a hydrophilic biodegradable polymer gelatin to reduce its release rate. Methods: An emulsification-coacervation method was adopted. "

Research and field experience with chlorine dioxide (ClO2) gas to decontaminate structures contaminated with Bacillus anthracis spores and other microorganisms have demonstrated the effectiveness of this sterilant technology. However, because of its hazardous properties, the unreacted ClO2, gas must …

"These results suggest that the ClO2, radical does not form the stable spin adducts with nitrone spin-traps, but oxidizes these spin-traps to give the corresponding nitroxyl radicals."

"A higher concentration of ClO2was required at pH 8 than at pH 5 to achieve a lethal dose resulting in 50% mortality of spores (LD50). The addition of the divalent metal ion solution required an increase in ClO2 concentration to maintain a LD50. When com-bined with the nitrogen and hard water solution, the divalent metal ion solution placed a higherdemand on ClO2 at pH 5 and a lower demand on ClO2at pH 8,"

"Chlorite dismutase (Cld) is a heme b-dependent, O–O bond forming enzyme that transforms toxic chlorite (ClO2−) into innocuous chloride and molecular oxygen. The mechanism and specificity of the reaction with chlorite and alternate oxidants were investigated."

***** {Very, very broad range of home uses for chlorine dioxide}

Compositions and methods for generating ClO2 gas are disclosed. A composition that includes a chlorite salt is activated by exposure to ultraviolet light. After an optional storage period,

A multilayer medical packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

Horticultural operations are facing increasing pressure to solve sanitation issues related to water treatment. Some of the pressure is external

"When independently tested ClearKlens Bi-Spore passes EN13704 with a contact time of 5 minutes, meaning that the extended contact time needed to ensure sporicidal-activity is eliminated. This result, combined with the low hazard to human health and the compatibility with different surfaces encountered in cleanroom environments, makes a chlorine dioxide generating system such as ClearKlens Bispore an ideal sporicidal disinfectant for use in pharmaceutical cleanrooms.

2007. "Endoscopes are immersed in 0.35 per cent per-acetic acid or 1100 PPM chlorine dioxide (ClO2) for 5 minutes. "

PERFORMACIDE® is a hospital grade disinfectant that effectively kills bacteria, viruses, mold and fungi in commercial buildings and other public places.

In this paper, the disinfection effects of chlorine dioxide (ClO2) on some main viruses, algae and animal planktons in water and the influence of ClO2…

pH is the hydrogen ion concentration present in a given solution. A low pH value denotes acidity, whereas a high pH value indicates alkalinity.

Oxidizing and reducing agents are key terms used in describing the reactants in redox reactions that transfer electrons between reactants to form products. This page discusses what defines an …

Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

Radioactive decay is the emission of energy in the form of ionizing radiation. Example decay chains illustrate how radioactive atoms can go through many transformations as they become stable and no longer radioactive.
