Abstract

Heavy metals are widely used in a range of materials including paints, motor vehicles, guns, and electrical components. After discarding such materials, the metal ions after dissolution can penetrate to the environment and are toxic to plants, organisms, and humans. Among such dangerous heavy metals belongs antimony. The aim of presented work was to study removal efficiency of antimony from waters using ferrate (VI). The experiments were performed for antimony in oxidation state III and V and the influence of ferrate(VI) to antimony ratio on antimony removal efficiency was studied. The experiments were performed under neutral pH value of the reaction mixture. The antimony concentration was determined using AAS method and residual concentration of antimony in reaction mixture was traced within two weeks. With increasing ferrate (VI) to antimony ratio from 10:1 to 60:1, the removal antimony efficiency slightly increased. However, even for ferrate(VI)to antimony equal to 10:1, the removal efficiency was after 30 minutes and after two weeks was even 80%. This means that the effectiveness of removal increase with prolonged contact time of components and no leaching of antimony back to aqueous solution proceed. The impact of concentration of some inorganic ions (nitrates, phosphates, sulfates, carbonates, and chlorides) usually present in real waters on antimony removal efficiency was also studied.
