| 1. A method of decontaminating materials contaminated with chemical or biological warfare agents consisting of the steps of:
preparing a first solution consisting of water, one or more monopersulfate compounds, and one or more buffers selected from
the group consisting of alkali metal salts of bicarbonate and carbonate; and
preparing a second solution consisting of one or more ketones, at least one of said ketones being selected from the group
consisting of acetone, 2-butanone, 2-pentanone, 2-hydroxy-4-methyl-2-pentanone, hexafluoroacetone, trifluoroacetone, acetophenone,
camphorsulfonic acid, and levulinic acid, wherein the first solution and the second solution are separately contained;
forming a decontaminating composition having a pH of from 5 to about 9, by mixing said first solution and said second solution
to achieve in situ generation of dioxirane in the composition; and
contacting said composition with materials contaminated by chemical or biological warfare agents.
