Over the past few decades, diverse chemicals and materials such as mono- and bimetallic nanoparticles, metal oxides, and zeolites have been used for soil and groundwater remediation. Ferrate (FeO) has been widely employed due to its high-valent iron (VI) oxo compound with high oxidation/reduction potentials. Ferrate has received attention for wide environmental applications including water purification and sewage sludge treatment. Ferrate provides great potential for diverse environmental applications without any environmental problems. Therefore, this paper provides comprehensive information on the recent progress on the use of (FeO) as a green material for use in sustainable treatment processes, especially for soil and water remediation. We reviewed diverse synthesis recipes for ferrates (FeO) and their associated physicochemical properties as oxidants, coagulants, and disinfectants for the elimination of a diverse range of chemical and biological species from water/wastewater samples. A summary of the eco-sustainable performance of ferrate(VI) in water remediation is also provided and the future of ferrate(VI) is discussed in this review.
在过去几十年中，各种化学物质和材料，如单金属和双金属纳米粒子、金属氧化物和沸石，已被用于土壤和地下水修复。高铁酸盐（FeO）因其具有高氧化还原电位的高价铁（VI）氧合化合物而被广泛应用。由于高铁酸盐在水净化和污水污泥处理等广泛的环境应用中受到关注。高铁酸盐在没有任何环境问题的情况下为各种环境应用提供了巨大的潜力。因此，本文提供了关于（FeO）作为绿色材料用于可持续处理过程的最新进展的综合信息，特别是用于土壤和水修复。我们综述了各种高铁酸盐（FeO）的合成配方及其作为氧化剂、混凝剂和消毒剂的相关物理化学性质，用于从水样中去除各种化学和生物物质。还总结了高铁酸盐（VI）在水修复中的生态可持续性能，并在本文综述中讨论了高铁酸盐（VI）的未来。
