The adsorption behavior and desorption method of aqueous Sb(III) on N201 supported by Fe(III) adsorbent material were examined by static and dynamic adsorption experiments. The results show that N201-Fe(III) on Sb(III) maximum static adsorption capacity is 610 μg/g, the best pH is 7, and the N201-Fe(III) resin is still highly selective for Sb(III) while coexisting with SO₄^2-, Cl^- in high concentration. The dynamic adsorption is capacity of 94.05 mg/L. EDTA is the best regenerative agent, under dynamic condition, its regeneration degree can be up to 85%.
