The Relative Efficiency of Various Scrubbing Techniques for Indoor Ozone Remediation
Corey R. Koch* and Matt A. Marks
Dr. Barbara K. Kramer, Faculty Mentor

Tropospheric ozone has been recognized as a health threat that can also have effects indoors. An indoor ozone-remediation technique may be useful to decrease ozone related health risks. Information on the efficiency of various ozone-remediation techniques could be useful for industrial application. Data will be presented on the efficiency of ozone removal techniques. A unique water/UV scrubbing method has been analyzed and has been found to decompose a constant percentage of ozone. Other industrially used ozone decomposition techniques that were analyzed are activated carbon, potassium iodide, and manganese dioxide. For these tests, ozone was detected using a continuous, indirect, and quantitative detection method, consisting of a KI/Boric acid absorbent solution and a UV/Vis spectrophotometer. The efficiency of these scrubbers was determined by finding the percent ozone decomposed and the time of significant decomposition relative to the amount of material used, waste produced, and cost of the technique.
