A method for decontaminating materials contaminated with toxic organophosphorous or organosulfur agents, comprising:
- a) providing a composition consisting essentially of:
- (1) a peracid or a salt of said peracid;
- (2) optionally, an aqueous solution with a buffered pH of 8 to 11;
- and
- (3) a cationic quaternary ammonium type surfactant,
- wherein said peracid is selected from the group consisting of:
- (i) an imidoperacid represented by general formula (I):
- ##STR3## wherein n is a whole number between 2 and 8 and R.sub.1 is a hydrogen atom, and
- (ii) a diperacid represented by general formula (II):
- HO.sub.3 C--(CH.sub.2).sub.p --CO.sub.3 H (II)
- wherein p is a whole number between 2 and 10;
- and
- b) contacting a material to be decontaminated with the composition.
A method for decontaminating materials contaminated with toxic organophosphorous or organosulfur agents, consisting essentially of:
- a) preparing a composition consisting essentially of:
- (1) a peracid or a salt of said peracid;
- (2) optionally, an aqueous solution with a buffered pH of 8 to 11;
- and
- (3) a cationic quaternary ammonium type surfactant,
- wherein said peracid is selected from the group consisting of:
- (i) an imidoperacid represented by general formula (I):
- ##STR4## wherein n is a whole number between 2 and 8 and R.sub.1 is a hydrogen atom, and
- (ii) a diperacid represented by general formula (II):
- HO.sub.3 C--(CH.sub.2).sub.p --CO.sub.3 H (II)
- wherein p is a whole number between 2 and 10;
- and
- b) placing the composition in contact with a material to be decontaminated.

- ##STR5## wherein n is a whole number between 2 and 8 and R.sub.1 is a hydrogen atom, and
- (ii) a diperacid represented by general formula (II):
- HO.sub.3 C--(CH.sub.2).sub.p --CO.sub.3 H (II)
- wherein p is a whole number between 2 and 10;
- and
- b) placing the composition in contact with a material to be decontaminated.
