| Abstract |
Electrolytic hydrolysis of toxic chemicals such as pesticide and nerve agent simulants was examined in the presence of catalysts that range from amino acids to functionalized surfactant and inorganic solids (zeolite, silica, and titanium dioxide). Hydroxide ions produced from cathode activate the catalysts by deprotonation of the active group, and proton ions around anode can not only neutralize hydroxide ions but make aqueous solution around anode strongly acidic enough to kill microorganisms. The cleavage rates of toxic chemicals have improved with the aid of catalysts: among the catalysts tested, functionalized surfactant shows exceptionally high cleavage rate against PNPDPP, and slight increase in cleavage rate was observed with the inorganic solid like zeolite. Cysteine was the most effective among amino acids for the deactivation of organophosphates. The sewage water from the Suwon area was also tested to result in the remarkable reduction, especially with titanium dioxide, in COD, decolorization, deodorization, and turbidity. The applicability of the electrolytic hydrolysis system for the deactivation of toxic chemicals in aqueous system and its modification needed are thoroughly studied in this paper. |
