Abstract : The chemical warfare agent sulfur mustard was hydrolyzed to products that were biologically mineralized in sequencing batch reactors seeded with activated sludge. Greater than 90% carbon removal was achieved using laboratory scale bioreactors processing hydrolyzed munitions grade sulfur mustard obtained directly from the U.S. Chemical Stockpile. The bioreactor effluent was nontoxic and contained no detectable sulfur mustard or priority pollutants. The sulfur mustard hydrolysis biodegradation process has potential application to the congressionally mandated disposal of sulfur mustard stockpiles.
