Abstract
A method for destroying chloropicrin in an aqueous medium contaminated with chloropicrin which comprises contacting the aqueous medium with a sufficient amount of an alkali metal sulfite for a sufficient period of time to convert the chloropicrin to an alkali metal chloride and to nitromethane disulfonic acid or a salt thereof, whereby the aqueous medium is rendered substantially free of chloropicrin.
