Abstract

Abstract:

Various affecting factors of methyl orange in the presence of nanometer TiO₂ powder prepared in laboratory on ultrasonic degradation have been studied. The results indicate the effects of ultrasonic degradation are more obvious in the presence of nanometer TiO₂ catalyst in the acidic condition irradiated with the ultrasound of 25 kHz frequency and power output of 50 W for about 80 min and the ratio of degradation can get to 98.6% and COD removal rate reaches 99.0% too.Thereby the ultrasonic degradation of organic pollutants catalyzed by nanometer TiO₂ catalyst has better applicable prospect.

Key words: nanometer titanium oxide, ultrasonic degradation, methyl orange

摘要：

采用合成的纳米TiO₂作为催化剂,以甲基橙超声降解反应为模型,研究了各种因素对TiO₂催化超声降解的影响。研究结果表明,在纳米TiO₂催化剂作用下超声降解甲基橙的效果非常明显。纳米TiO₂催化剂用量在1.0~1.5g/L之间,超声波频率25kHz,输出功率50W,pH为3.0时,甲基橙水溶液初始质量浓度20mg/L的条件下,通过分光光度法测定,80min左右基本可全部降解,降解率为98.6%,COD的去除率达到了99.0%。因此,纳米TiO₂催化超声降解有机污染物的方法具有很好的应用前景。
