Schwertmannite is a typical iron-derived mineral, which was originally discovered in acid mine drainings and subsequently synthesized in the laboratory. Increasingly, it is seen as having considerable potential as an adsorbent material, which could be used for environmental remediation (such as the treatment/remediation of arsenic, chromium, antimony, fluoride, and organic contaminants). This study reviews current developments, mainly in the preparation, structure, and water treatment of Schwertmannite. Several key issues are discussed in detail, such as synthetic strategy, the structure-property relationships, potential environmental applications, and related mechanisms. Soil remediation by schwertmannite is compared to water treatment, and its application is further evaluated. Finally, the methodologies for water treatment and soil remediation using schwertmannite are also taken into consideration from an environmental point of view.
施韦特曼石是一种典型的铁衍生矿物，最初在酸性矿山排水中被发现，随后在实验室中合成。越来越多的人认为它作为一种吸附材料具有相当大的潜力，可用于环境修复（如处理/修复砷、铬、锑、氟化物和有机污染物）。本研究综述了施韦特曼石目前的研究进展，主要涉及制备、结构和水处理方面。详细讨论了几个关键问题，如合成策略、结构-性能关系、潜在的环境应用及相关机制。将施韦特曼石用于土壤修复与水处理进行了比较，并对其应用进行了进一步评估。最后，还从环境角度考虑了使用施韦特曼石进行水处理和土壤修复的方法。
