摘要
新型冠状病毒肺炎(COVID-19)疫情给人类社会发展和生命健康造成了巨大威胁,由于新型冠状病毒(SARS-CoV-2)在水中的稳定性,城市污水成为该病毒最集中的污染源之一,因此如何杀灭主要水媒介中的病毒也成为了科学领域关注的重要问题。新冠病毒在结构上由具有遗传效应的RNA链和蛋白衣壳组成,可受活性氧物种(ROS)攻击解体而被灭活。生化代谢的阻断和结构的破坏也是新冠病毒灭活的有效方法。纳米材料因其表面和界面效应、独特的微观结构及优异的物化性质,在新冠病毒杀灭中有很好的应用前景。本文在探讨新型冠状病毒结构组成以及其在水环境中的存活及传播特征的基础上,全面综述了纳米材料在光催化、非均相催化高级氧化、离子毒性灭活和结构效应等方面于灭活病毒中的应用,深入探究了病毒灭活行为及机理。基于此,结合新冠病毒的结构组成及传播特征,深入探讨了不同纳米技术的新冠病毒灭活中的潜在应用。该综述可为环境纳米技术应用于水中新冠病毒灭活及其在水媒介中的次生传播阻断提供理论依据和实践参考。
The novel coronavirus pneumonia epidemic(COVID-19) brings a serious threat to the development of human society and the health of human beings. Due to the stability of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) in urban sewage, which has become one of the virus pollution sources, it has been a focus how to eliminate the existing virus in water. SARS-CoV-2 structurally consists of RNA chains and protein capsids, and thus can be inactivated via reactive oxygen species(ROS) attack. Moreover, block of biochemical metabolism and destruction of virus structure are also effective inactivation methods for SARS-CoV-2 inactivation. Nanomaterials exhibit surface and interface effects, specific microstructure and excellent physicochemical properties, implying their high application potential in SARS-CoV-2 inactivation. In this study, we overall review application of nanotechnologies for SARS-CoV-2 inactivation, including photocatalysis, heterogeneous catalytic oxidation, ion toxicity induced inactivation, and structural effects inactivation method. Furthermore, based on the structural composition, as well as survival and transmission characteristics of SARS-CoV-2 in water environment, the application potential of various nanotechnologies for SARS-CoV-2 inactivation are deeply discussed. This study can provide a theoretical basis and practical reference for the application of nanotechnology for the SARS-CoV-2 inactivation and the secondary transmission interruption in water.
