过氧化氢增强紫外光催化臭氧降解水中偏二甲肼的动力学研究

Kinetics of Degradation of Unsymmetrical Dimethylhydrazine in Water by Hydrogen Peroxide Enhanced Ultraviolet Photocatalytic Ozone

利用过氧化氢-臭氧-紫外(H_2O_2-UV-O_3)氧化体系降解偏二甲肼(UDMH)的模拟废水,采用竞争动力学法,以硝基苯(NB)为参比有机物,获得了偏二甲肼与臭氧(O_3)和羟基自由基(·OH)的反应速率常数。

The reaction rate constants of unsymmetrical dimethylhydrazine(UDMH)with ozone(O3)and hydroxyl radicals(OH)were obtained by competitive kinetics using nitrobenzene(NB)as a reference organic compound and hydrogen peroxide-ozoneultraviolet(H2 O2-UV-O3)oxidation system to degrade UDMH simulated wastewater.
