随着全球人口的不断增加，供水压力将不可避免地加剧。因此，国际上对更有效和更具成本效益的水补救技术的需求也将增加。将纳米技术引入该行业可能代表了一个重大进步，零价铁纳米颗粒（INPs）已被彻底研究用于潜在的修复应用。然而，水分散的INP悬浮液的应用是有限的，并且在安全性方面有些争议，而INP的反应机制、传输特性和生态毒性仍在研究中。从理论上讲，开发含有INPs的纳米复合材料来克服这些问题，为开发更适合在水行业广泛应用的纳米材料提供了合乎逻辑的下一步。本综述概述了正在开发的含有INPs的静态散装纳米复合材料的范围，同时强调了单个解决方案的局限性，整体技术类别以及缺乏纳米复合材料的比较测试。该综述讨论了优化纳米复合水修复系统以实现商业成熟所需的进一步发展。
As global populations continue to increase, the pressure on water supplies will inevitably intensify. Consequently the international need for more efficient and cost effective water remediation technologies will also rise. The introduction of nano‐technology into the industry may represent a significant advancement and zero‐valent iron nano‐particles (INPs) have been thoroughly studied for potential remediation applications. However, the application of water dispersed INP suspensions is limited and somewhat contentious on the grounds of safety, whilst INP reaction mechanisms, transport properties and ecotoxicity are areas still under investigation. Theoretically, the development of nano‐composites containing INPs to overcome these issues provides the logical next step for developing nano‐materials that are better suited to wide application across the water industry. This review provides an overview of the range of static, bulk nano‐composites containing INPs being developed, whilst highlighting the limitations of individual solutions, overall classes of technology, and lack of comparative testing for nano‐composites. The review discusses what further developments are needed to optimize nano‐composite water remediation systems to subsequently achieve commercial maturity.
