硝基苯水溶液的超声波降解动力学

The dynamics of ultrasonic degradation was investigated for nitrobenzene solution. The highly apparent first-order degradations under four ultrasonic powers were measured by the least square method. The rate constants, the relationship of rate constant and ultrasonic power and the dynamic equation were also determined. The removals of TOC of the sample and degradation products were studied at the same time. 2-nitrophenol and 4-nitrophenol were found as degradation products by GC-MS during the degradation of nitrobenzene. The possible pathway of ultrasonic degradation of nitrobenzene was also discussed.
