Abstract

Water safety is one of the major environmental issues. Drawbacks of the conventional disinfection methods necessitate alternative, novel, low-cost, safe and highly efficient disinfection methods. With the advancements in nanotechnology, excellent antibacterial properties of nanosilver started to be used extensively in disinfecting medical devices, food packaging, clothing-fabrics and water-air disinfection. Recent studies showed that nanosilver-based materials used as disinfectants are highly promising to replace or to enhance the effectiveness of the conventional water disinfection methods. This is because, nanosilver-based materials do not generate carcinogenic disinfection-by-products (DBPs), require less energy, have no clogging problem, and achieve high removal efficiencies. In order to develop and improve disinfection methods with nanosilver-based materials, it is fundamental to understand the factors affecting their water disinfection performance. This review article, for the first time, focuses on the major factors affecting the water disinfection performance of nanosilver-based materials such as microbial culture, flow rate, silver concentration and water characteristics. The factors affecting silver release were also discussed. Understanding of these factors would certainly improve the development of nanosilver-based technologies. The compilation of the results presented herein will be helpful in guiding researchers who aim to work on this subject.

摘要

水安全是主要的环境问题之一。传统消毒方法的缺点需要替代、新颖、低成本、安全和高效的消毒方法。随着纳米技术的进步，纳米银优异的抗菌性能开始广泛应用于医疗器械、食品包装、服装面料和水空气消毒等领域。最近的研究表明，用作消毒剂的纳米银基材料非常有希望取代或提高传统水消毒方法的有效性。这是因为，纳米银基材料不会产生致癌的消毒副产物 (DBP)，需要的能量更少，没有堵塞问题，并且去除效率高。为了开发和改进纳米银基材料的消毒方法，了解影响其水消毒性能的因素至关重要。这篇综述文章首次重点介绍了影响纳米银基材料水消毒性能的主要因素，如微生物培养、流速、银浓度和水特性。还讨论了影响银释放的因素。了解这些因素肯定会促进纳米银技术的发展。此处介绍的结果汇编将有助于指导旨在研究该主题的研究人员。重点介绍了影响纳米银基材料水消毒性能的主要因素，如微生物培养、流速、银浓度和水特性。还讨论了影响银释放的因素。了解这些因素肯定会促进纳米银技术的发展。此处介绍的结果汇编将有助于指导旨在研究该主题的研究人员。重点介绍了影响纳米银基材料水消毒性能的主要因素，如微生物培养、流速、银浓度和水特性。还讨论了影响银释放的因素。了解这些因素肯定会促进纳米银技术的发展。此处介绍的结果汇编将有助于指导旨在研究该主题的研究人员。
