Sonochemical degradation of hazardous organic compounds in aqueous solution has been examined extensively in recent years and found to be an effective means of waste treatment however the scavenging of hydroxyl radicals by the relatively high concentrations of hydrogen peroxide produced limits the amount of reactive radicals accessible to target molecules. In this project we will investigate, by both experimental and computational means, options for the regeneration of hydroxyl radicals through use of hydrogen peroxide. Methods of particular interest include use of Fenton's reagent and ozone.

水溶液中有害有机化合物的声化学降解近年来已被广泛研究，并发现是一种有效的废物处理手段，然而，通过产生的相对高浓度的过氧化氢清除羟基自由基限制了目标分子可接近的反应性自由基的量。在这个项目中，我们将调查，通过实验和计算手段，通过使用过氧化氢的羟基自由基的再生选项。特别感兴趣的方法包括使用芬顿试剂和臭氧。
