- Abstract
The soil distribution coefficient for highly concentrated TNT soil is determined. Different amounts of TNT soil are shaked with 250 ml of distilled water, and the concentration of TNT in water is monitored throughout the experiment. At the conclusion of the experiment, the remainder of TNT in the soil is determined. The soil distribution coefficient is calculated by dividing the concentration of TNT in the soil by the concentration of TNT in the water phase. The average soil distribution coefficient is found to be 4.86 L/kgThe mass transfer coefficient was determined under static conditions. This experiment involves a comprehensive study of distribution profiles for TNT in the soil and solvent phases. The experiment was conducted under a controlled temperature environment, for extensive periods of time. Samples were collected on a regular basis and were analyzed promptly. The average value of the mass transfer coefficient was determined to be 3.4×10-3 hr-1.
