Ozone in water half life
WebNov 24, 2024 · The real negatives are listed below: Half Life: Ozone is an unstable molecule which quickly changes back to oxygen. The time for half of the ozone in airto decompose (half-life) can vary from an hour to three days, depending on the temperature, humidity and movement of the ambient air. The half-life in water is usually 30 minutes or less ... WebOct 1, 2004 · The cleaner the water, the longer the ozone half-life. In clean water used to wash food, ozone lasts several hours, while dirty water can shorten ozone’s half-life to seconds. As the pH of ozone-containing solutions increases, the rate of ozone decomposition also increases.
