| Abstract: | Nano-TiO2/chitosan ultrasonic degradation catalysts was synthesized and its structure characteristics was analyzed by IR and XRD.Ultrasonic degradation of methyl orange in the presence of nano-TiO2/chitosan catalyst were studied.The researched results indicate the effects of ultrasonic degradation were more obvious in the presence of 1.0g/L nano-TiO2/chitosan irradiated with the ultrasound of 40kHz frequency and 50W power input about 60 min and the degradation rate of methyl orange can get to 90%(pH=7.0).Th... |
