Abstract

The migration/transformation properties and laws of sodium pentachlorophenol (PCP-Na) in loess soil under the saturated conditions have been studied by one-dimensional dynamic soil column experiments, the transport model of PCP-Na and its model parameters have been obtained, and tested the validation of mathematical models. Real mathematical model results in good agreement with experimental results, indicating that the hydrodynamic dispersion model could be used to simulate the migration of pentachlorophenol in the loess soil. The spatial and temporal distribution of PCP-Na concentration in the loess soil and the pollution to groundwater could be predicted by the mathematical model.
