MuniRem® › What it treats
Lead azide / dextrinated lead azide (DLA)
What Lead azide / dextrinated lead azide (DLA) is, and how we evaluate it with MuniRem®.
What it is
Lead azide is a primary explosive used in detonators. Dextrinated lead azide (DLA) is a form mixed with dextrin to make it safer to handle. It detonates from small shocks or static, and it contains toxic lead.
How MuniRem® treats it
MuniRem lists lead azide as an explosive it treats. No data was found on DLA, and no lead azide reaction or end products were published. MuniRem's general metals chemistry would bind the lead as an insoluble sulfide.
- MuniRem arrives as a dry powder. Crews mix it into contaminated soil or sludge, or dissolve it in water to spray, pour or soak surfaces.
- Adding water starts the reaction. The reagent releases sulfoxyl free radicals, a short-lived reactive form of sulfur.
- The lead reacts with sulfur from the reagent to form insoluble lead sulfide. What happens to the azide part is determined by treatability study.
- An EPA-certified laboratory tests the treated material before any disposal decision.
This material is evaluated case by case with a treatability study before any full-scale work.
What it becomes
Lead as insoluble lead sulfide, Azide part: determined by treatability study.
Where it's found
Detonator and primer plants and demilitarization lines.
