Abstract :
Arsenic displays complex nature in groundwater. The study of geochemical properties of arsenic in groundwater enables not only the prediction of arsenic pollution trend in groundwater, but also the prevention and mitigation of arsenic pollution. This article is mainly about using soil column dynamic experiment to simulate the arsenic kinetic behavior when it migrates in groundwater environment. Studies have shown that the migration rate of arsenic is 0.0094 times as fast as groundwater. In addition, reaction rate constant decreases gradually with the increase of pore volume of intake water. According to dynamic simulation analysis, it can be concluded that the zero order kinetic model is a best one to properly describe the migration of arsenic in soil column.
