| Abstract: | Simulated reactive blue KN-R wastewater was treated using TiO2 as photocatalyst and two UV light sources with 365 nm and 254 nm of wavelength.The effects of wavelength and radiation intensity were studied.The experimental results show that: After radiation under 365 nm UV-light for 2 h,the degradation rate of reactive blue KN-R is 69.1%,and the degradation of reactive blue KN-R can fit the second order reaction rate equation;After radiation under 254 nm UV-light for 1 h,the degradation rate of reactive blue... |
