摘要：

Ferrate(VI) [(FeO42-)-O-VI, Fe(VI)] has excellent disinfectant properties and can inactivate a wide variety of microorganisms at low Fe(VI) dosages. The final product of Fe(VI) is Fe(III), a non-toxic Compound. The treatment by Fe(VI) does not give any chlorination by-products, which makes Fe(VI) an environmentally-friendly ion. The results demonstrate that Fe(VI) can inactivate Escherichia coli (E. coli) at lower dosages or shorter contact time than hypochlorite. Fe(VI) can also kill many chlorine resistant organisms, such as aerobic spore-formers and sulphite-reducing clostridia, and would be highly effective in treating emerging toxins in the aquatic environment. Fe(VI) can thus be used as an effective alternate disinfectant for the treatment of water and wastewater. Moreover, Fe(VI) is now becoming economically available in commercial quantities and can be used as a treatment chemical to meet the water demand of this century. This paper reviews the potential role of Fe(VI) as disinfectant in water and wastewater treatment processes.
