中文摘要：

采用高温活化处理过的纳米氧化锌（ZnO）粉末为催化剂，研究了超声照射对酸性红B的降解．另外，还考查了超声照射时间，酸性红B初始浓度和纳米ZnO的添加量对酸性红B降解反应的影响．结果表明：在纳米ZnO作用下，酸性红B的超声降解效果明显优于单纯超声波照射降解．降解动力学符合一级反应．在超声波频率40kHz，输出功率50W，催化剂用量1．0g／L,pH为7．0，温度25℃，酸性红B水溶液初始浓度10mg／L的条件下，照射120min左右时降解率即可达到86％以上．

英文摘要：

Some factors such as ultrasonic irradiation time, initial concentration of acid red B and addition amount of ZnO on ultrasonic degradation of Acid Red B was studied with nanometer ZnO catalyst activated at high-temperature. The results indicated that the effects of sonocatalytic degradation were more obvious in the presence of nanometer ZnO. The ultrasonic degradation kinetics of Acid Red B in the presence of nanometer ZnO catalyst follows first-order reaction. The degradation ratio of Acid Red B surpassed 86% within 120 min under conditions of ultrasonic frequency of 40 kHz, power input of 50W, amount of catalyst of 1.0 g/L, pH = 7, temperature of 25℃ and Acid Red B concentration of 10 mg/L.
