Antimony (Sb) has received increasing environmental concerns due to its potential toxic and carcinogenic properties. In the present
work, the electrocoagulation technique was used to treat the flotation wastewater from a heavy antimony polluted area, and the
mechanism of removing Sb was also investigated. The study focused on the effect of operation parameters such as current density,
initial pH and standing time on the Sb removal efficiency. Antimony concentration of below 1 mg/L in the treated wastewater was
achieved, which meets the emission standards established by State Department of Environmental Protection and State Administration
of China for Quality Supervision and Inspection and Quarantine of China.
