- Résumé
- "Ozone gas can be used to remove odour and is particularly effective for removing smoke and musty smells from books. Disaster remediation companies are known for using this treatment to remove odour from artifacts. The process, however, involves the uncontrolled release of highly reactive ozone molecules into the vicinity of the object; these molecules deactivate the particles causing odour, but are also likely to oxidize materials in the artifact, resulting in deterioration. The goal of this project is to investigate how the structure of cellulose is affected when paper is exposed to ozone in high but short doses. Samples of Whatman filter paper were tested, and the change in cellulose strength was measured by determining the copper number of the paper before and after ozone exposure, a measure which indicates deterioration levels. The paper samples were exposed to ozone gas at a concentration and duration comparable to that used in the restoration industry, and a second batch exposed in conditions exceeding normal treatment levels. A separate sample was bleached with hydrogen peroxide, a treatment also known to cause oxidation of cellulose but considered acceptable when weighed against improvement to the artifact; the copper number of this sample was determined and compared with the ozone treated papers. The results of this research, while not entirely clear, do indicate that the amount of oxidative damage inflicted on cellulose by ozone gas, in the levels used for odour removal, is not significantly higher than that caused by a mild oxidizing bleach."
