Abstract

The Bi2O3 thin films were prepared by sol-gel method for photocatalytic degradation of unsym-dimethylhydrazine (UDMH) wastewater. The effects of initial concentration of UDMH, initial pH value of solution and H2O2 addition were investigated. Besides, the reaction kinetics and mechanism were studied. The results showed that when the initial concentration of UDMH was between 100 mg/L and 500mg/L, the concentration had little effect on the degradation efficiency; initial pH value of solution had noticeable impact on the degradation of UDMH and higher removal efficiency can be achieved in neutral or weakly alkaline condition; the addition of H2O2 can effectively improve the degradation. The kinetic study showed that the reaction kinetics were well fitted by the pseudo first-order rate model and Langmuir-Hinshelwood model.
