摘要：
A mathematical and computer model for the transport and transformation of arsenic through a soil column from the surface to the groundwater is presented. The model simulates arsenic species. This model is based on the mass balance equation including convective transport, dispersive transport, surface adsorption, oxidation and reduction, volatilization, chemical and biological transformation. The governing equations are solved numerically by the method of implicit finite difference. The simulation results are in good agreement with measured values. The major finding in the present study indicates that as the time of simulation increases, the concentration of different arsenic species approaches the measured values.
