Adsorption of 2,4,6-trinitrotoluene and 4-amino-2,6-dinitrotoluene in two soil environments
- Georgia Inst. of Technology, Atlanta, GA (United States)
Soil contamination by 2,4,6-trinitrotoluene (TNT) and its byproducts is common among Army Ammunition Plants (AAPs). The purpose of this research is to quantify the behavior of TNT in the Alabama AAP soil environment. Uncontaminated soil collected from two different depths at the site was used, one with relatively high organic content and one with low organic content. Adsorption kinetic tests for both TNT and a primary biotransformation byproduct 4-amino-2,6-dinitrotoluene (4A26DNT), alone and in combination, were performed and adsorption isotherms were developed. Results indicate a faster rate of adsorption for 4A26DNT than for TNT, as well as a larger extent of adsorption when the two compounds are both present. As expected, incubation time was shown to affect the extent of adsorption as well as the extractability and transformation of TNT. Large differences in kinetic patterns were obtained for each soil. Isotherm shape was similar for both soils, however extent of adsorption differed by several orders of magnitude.
