空化水中HO2自由基的捕获

摘要

@@ 1 INTRODUCTIONrnAs a new advanced oxidation process (AOP) in water treatment, sonochemistry in water treatment has been paid more attention for one decade[1-7]. The collapsed cavitation bubbles give rise to high temperature and high pressure[8] to generate free radical, e.g. OH, O, HO2 in sonicated water. These kinds of radicals can oxidize the organic substances dissolved in water.
