Relationship Between the Leachability Characteristics of Unique Energetic Compounds and Soil Properties
Abstract
The object of this project was to develop a soil sorption model for hexahydro-1,3,5trinitro-1 3,5-triazine (RDX) and 2,4,6-trinitrotoluene (TNT) based on physical-chemical properties of soils in the absence of biotic and abiotic transformation/degradation of the solutes. This was accomplished by conducting a series of batch and column studies with TNT and RDX on a variety of sterilized soils. Abiotic transformation of TNT to several amino compounds, of which 2 amino-4,6-dinitrotoluene was the most common, necessitated direct analysis of the solute in the aqueous phase and extraction/analysis of the sorbed material to be performed on all batch studies to allow for mass balance calculations. RDX was poorly sorbed to all soils, and steady-state conditions were obtained within 6 h. Linear sorption coefficients (Kd) were generally < 1ML/g. The sorption and desorption limbs of the breakthrough curves were symmetrical and solute breakthrough could be well described by the use of a transport code that accounted for dispersion and fast, reversible sorption described by a linear isotherm....
