Abstract
The mechanism of thermally- or hydrogen peroxide-initiated decomposition of acidic O3 solutions was investigated. Specifically, the role of hydrogen peroxide in the acidic zone decomposition process was examined to determine the nature of the initiating and terminating species and their reactions. Experimental results showed that thermal or hydrogen peroxide-initiated decomposition of acidic aqueous ozone is a chain process propagated by OH and O2(super -)/HO2 radicals. The chain is initiated by surface-catalyzed formation of hydrogen peroxide when hydrogen peroxide is not added.
