研究了超声波对苯酚的降解以及几个参数--静水压力、溶解气体性质、超声波频率--的影响。主要降解产物为二羟基苯和苯二酚。随着时间的推移，这些产物会进一步降解为低分子羧酸。添加雷尼镍可以增加COD的还原。利用高效液相色谱和高效毛细管电泳法对降解产物进行了分析，提出了反应方案。
The degradation of phenol with ultrasound and the influence of several parameters - hydrostatic pressure, nature of the dissolved gas, frequency of the ultrasound - have been studied. Primary degradation products are dihydroxy benzenes and quinones. These products are further degraded upon time into low molecular carboxylic acids. COD reduction can be increased by the addition of Raney nickel. Based on the determination of the degradation products by HPLC and HPICE, a reaction scheme can be suggested.
