Title
Catalytic detoxification of 1,1-dimethylhydrazine aqueous solutions in heterogeneous Fenton system
Abstract

The experimental study into catalytic properties of FeZSM-5 was undertaken into oxidation of 1,1-dimethylhydrazine (UDMH) aqueous solutions using hydrogen peroxide. The performances of heterogeneous and homogeneous Fenton systems were compared. UDMH complete mineralization was achieved. Formic and acetic acids, as well as nitromethane, were identified as oxidation by-products. Adsorption properties of FeZSM-5 with respect to hydrogen peroxide, 1,1-dimethylhydrazine and N-nitrosodimethylamine have been studied. The effects of the oxidant and the target compound concentrations, temperature and pH of aqueous solution were established.
