Abstract In this study, batch experiments and characterization analysis were conducted to explore the characteristics and mechanism of MTA adsorption on soil by adding different concentrations of phosphate. Results showed that:the Elovich kinetic model and Langmuir isothermal adsorption model can better fit the adsorption process of MTA on soil, indicating that the adsorption process of MTA was mainly affected by the diffusion of pore size. The maximum adsorption capacity of MTA on soil was 254.214mg/kg. With the increase of the initial concentrations of adding phosphate in the solution, the equilibrium adsorption capacity of MTA on soil gradually decreases, and that of phosphate gradually increases. SEM-EDS results showed that a small amount of As was detected on the surface of soil whether adding phosphate or not. In the system with phosphate addition, the soil showed a relatively low content of As, confirming that the presence of phosphate can reduce the adsorption of MTA on soil. In addition, XRD results showed that MTA can form endosphere complexes of -[2Al(H₂AsO₄)₃],≡Al₂O₂AsO(SH) and -[2Fe(H₂AsO₄)₃] with Fe-Al minerals in soil samples, and phosphate can form endosphere complexes with hydroxyl groups on the surface of soil, weakening the adsorption of MTA.
