Coupling advection–dispersion equation and dynamic model for phytoremediation of 134Cs in soil
This study proposes a model for phytoremediation coupling transport in soil and dynamic model using sunflower plants and 134Cs radionuclide. The model was validated by comparison with experimental measurements. The error value obtained, ranging from 0.00045–0.5268, is quite small, and the overall simulation data has approached the experiment. Factors influencing radionuclide concentration in different blocks include saturation point values, absorption rates of plant parts, soil dispersion coefficient, and velocity. The model is used to predict doses from ingesting sunflower seeds and estimates the soil-to-plant transfer factor. This new model is recommended for accurate assessment of environmental risks associated with radionuclides and for efficient decontamination.
