Paper Abstract

We report on scanning electron microscopy and energy disperse X ray fluorescence measurements of TNT deposits on dry, wet and basic Ottawa sand particles. On clean Ottawa sand particles, TNT deposits form elongated crystals that change the morphology with time. The surfaces of the crystals acquire roughness features in one month old deposits and are no longer observed in two month deposits. On wet surfaces, fresh TNT deposits form assembles that resemble wire meshes. One month old TNT deposits on wet Ottawa sand appear to cover the particles surfaces and are no longer observed in structures that resemble the crystals observed on dry deposits. Fresh TNT deposits on Ottawa sand pre treated with sodium hydroxide appear amorphous. The deposits appear to cover the particle surfaces after a month and break into thin fibers in two month old deposits.
