UV-Fenton Oxidation for Treatment of UDMH Wastewater and Kinetic Studies

摘要：

1, 1-Dimethylhydrazine (UDMH) is the principal component of liquid propellant, which has been classified as a third class toxicant. The experimental study of oxidation of UDMH aqueous solution using UV-Fenton process was undertaken. In this study, two main UDMH degradation conditions which were initial H202 concentration and initial Fe2+ concentration were investigated. The experiment results showed that 4758.3mg/L H2O2 and 1296.9 mg/L FeSO4.7H2O arc the optimal experiment conditions for the UDMH UV-Fenton degradation process, and under this conditions the UDMH degradation rate can reach 99.6％. The kinetic model of UDMH degradation rate was established in this study, which were under the reaction conditions of solely ultraviolet and of UV-Fenton respectively.
