Abstract
In various embodiments, methods of treating a space to reduce a concentration of volatile organic compounds present in the space using chlorine dioxide are provided. A method can include application of aqueous and gaseous chlorine dioxide solutions within the space or to materials located within the space. Treatment of materials that emit volatile organic compounds with chlorine dioxide can reduce the emission rate or shorten the volatile organic compound emission cycle of the material. Soft surface substrates such as carpeting materials can be treated with chlorine dioxide to reduce volatile organic compound emission and/or to reduce the number of microorganisms present in the material.
Claims19
A method of treating a space to reduce a concentration of a volatile organic compound (VOC) comprising:
- determining a first concentration of a first VOC at a first time;
- and
- applying a chlorine dioxide treatment in the space for a treatment period in response to the first concentration of the first VOC, wherein:
- the chlorine dioxide treatment is compatible with human occupancy of the space during the treatment period;
- and
- the chlorine dioxide treatment is effective to reduce the first concentration of the first VOC to a second concentration of the first VOC at a second time that is lower than the first concentration of the first VOC.
A method of reducing a volatile organic compound (VOC) emission rate of a material comprising:
- determining a first VOC emission rate of a material at a first time;
- applying a chlorine dioxide treatment to a material to produce a treated material;
- and
- determining a second VOC emission rate of the treated material at a second time;
- wherein the chlorine dioxide treatment accelerates a VOC emission decay rate of the material to produce a reduced VOC emission rate of the treated material, wherein the second VOC emission rate of the treated material is lower than the first VOC emission rate of the material.
A method comprising:
- treating a substrate with a chlorine dioxide treatment in situ in a space for a treatment period;
- wherein the space comprises one of a residential space or a commercial space;
- wherein the chlorine dioxide treatment is compatible with human occupancy of the space during the treatment period;
- wherein the chlorine dioxide treatment is effective to reduce an emitted TVOC quantity in the space as compared to an untreated substrate in an equivalent space;
- and
- wherein the chlorine dioxide treatment does not produce a detrimental impact on the substrate.
