Diffusive transport of 2, 4, 6-trinitrotoluene (TNT) from contaminated soil to overlying water

摘要

Understanding the transport mechanism of 2, 4, 6-trinitrotoluene (TNT) and other compounds is necessary in order to implement an effective phyto-or bioremediation scheme for explsives-con- taminated soil. The transport of TNT from two contaminated soils into overlying water was investigated using a laboratory sheet-flow leaching bed reactor (SLBR). Soil I had a low contamination of TNT (11 ± 1 mg kg~-1), whereas Soil II had very high contamination of TNT (22 874 ± 518 mg kg~-1).
