摘要

1-(4-Chlorophenyl)-N-hydroxymethanimine and cyclohexyl-N-hydroxymethanimine were synthesized and loaded over acid treated carbon. Thereafter, these impregnated carbon systems were characterized. Kinetics of the degradation of sarin and its simulant, i.e., diethylchlorophosphate were monitored and found to be following pseudo first order reaction kinetics. The order of reactivity of the prepared carbon systems was 1-(4-chlorophenyl)-N-hydroxymethanimine/C > cyclohexyl-N-hydroxymethanimine/C > acid treated carbon. Hydrolysis reaction was found to be the route of degradation of diethylchlorophosphate and sarin. On the basis of the reaction products, a plausible reaction mechanism is proposed.
