The mining and smelting of vanadium deposit can cause heavy metal contamination of the soil, but there were few researches about remediation of vanadium deposit contaminated soil. Four kinds of iron-based liquid solidifying agents, including ferrous chloride, ferrous sulfate, ferric chloride, ferric sulfate, were added to the vanadium deposit contaminated soil for the stabilization of heavy metals. The results showed that the stabilization efficiency of the liquid iron-based agents on vanadium was high reaching 100.00% in 7 days. The optimal dosage of the agents was 0.5wt% m/m, and the most effective agent was ferrous sulfate. The efficiency was still high by 120 days. The ferrous agents were also effective in the stabilization of chromium. The ferrous chloride showed a stable stabilization efficiency of about 98.0% by 120 days. Because of the influence of pH, excess agents increased the leaching of Cd, Zn, Cu in 15 days. The leaching concentration decreased over time and was similar to the soil without stabilization at day 120.
