Waste water from ammunition disposal can be of high volumes and heavily contaminated with toxic substances such as explosives and heavy metals. In the present paper, a contaminated waste water from a Swedish disposal industry was treated with the organic byproduct pine bark (Pinus Silvestris) as an adsorbent for capture of primarily the very common explosives substance TNT (2,4,6-trinitrotoluen). Traditionally, TNT is primarily a military explosive, and the source can be leaching from production, disposal or stockpiles of ammunition. TNT is toxic, both acute and chronically, and resistant to natural microbiological degradation why it can cause severe effects to an eco-system.
