Sonochemical Degradation of Polychlorinated Biphenyls in Aqueous Solution
摘要
Polychlorinated biphenyl (PCB) is a kind of persistent and dangerous environmental pollutants. This paper presented the research result of sonochemical degradation of 2-chloro- biphenyl (2-CBP), 4-chlorobiphenyl (4-CBP) and 4,4'-dichlorobiphenyl (4,4'-CBP)in water. The ultrasonic degradation kinetics of 2-CBP, 4-CBP and 4,4'-CBP in water were found to be first-order and the degradation rate coefficients are 3.69×10-2, 3.19×10-2 and 2.06×10-2 at 25±1°C for 2-CBP, 4-CBP and 4,4'-CBP respectively. The influence of initial concentrations, reaction temperature on the ultrasonic decomposition of 2-CBP were also investigated.
