Abstract: This study focuses on the adsorption characteristics of zinc in soil at different depths of a certain abandoned rare earth mine in the south of Ganzhou, Jiangxi Province. Static batch experiments were conducted. X-ray diffraction (XRD) and X-ray absorption fine structure spectroscopy (XAFS) were used to study the major phases and morphological changes of zinc in soil before and after adsorption reaction, in order to investigate the adsorption mechanism and mobility of zinc in soil. The results show that the adsorption equilibrium process of zinc in soil is fast. The adsorption capacity of soil for zinc gradually decreased from the surface soil to the deep soil and then to the middle soil. The pseudo-second-order kinetic model and Langmuir equation can describe the adsorption process of zinc in soil well. XRD and XAFS results show that iron and manganese exist mainly in the form of iron hydroxide and mixed valence state manganese oxide in soil. Differences in the physical and chemical properties of soil layers affect the adsorption behavior of soil towards zinc. Compared with clay minerals, iron and manganese oxides have a more significant effect on the adsorption of zinc in soil. XAFS indicates that the local coordination mode of zinc changes from Zn-O tetrahedron to a mixed coordination mode of Zn-O tetrahedron and octahedron after adsorption reaction. A complex similar to sulfate may form on the soil surface after the reaction. The form of zinc in soil changes from basic carbonate to a mixed form of sulfate and basic carbonate after adsorption reaction. Due to the influence of soil pH, the capacity of zinc retention in soil is limited. The readily available zinc in soil is prone to migrate downward with rainfall. The zinc content in soil increases with depth. The study provides a scientific basis for the prevention and control of zinc pollution in soil and groundwater in mining areas.
