摘　　要：纳米银因卓越的抗菌性能被广泛用于纺织品生产中。然而,在纺织品洗涤过程中,大量的纳米银会释放并进入到洗衣废水中。不同的洗涤条件决定了释放出的纳米银的团聚及溶解行为,进而影响后续环境过程并对水生生物及生态系统产生负面影响。为探究不同洗涤条件对纳米银团聚及溶解行为的具体影响,降低纳米银所带来的环境风险,文章归纳了国内外相关研究文献,在分析洗衣废水特点的基础上,讨论了废水中洗涤剂种类、光照、pH值、离子强度等条件对纳米银团聚及溶解行为的单独或联合作用与影响机理,并根据机理提出了减小纳米银生物毒性的建议,包括减少洗涤过程中纳米银的释放及洗衣废水处理方法的改善,最后对洗衣废水中纳米银未来的研究方向进行展望,提出了后续研究建议。Silver nanoparticles have been widely used in textiles because of excellent antibacterial properties to inhibit the growth of bacteria and pathogenic microorganisms.However,the massive use of silver nanoparticles can also cause harm to the ecological environment.During the textile washing process,a large amount of silver nanoparticles will be released and enter the laundry wastewater.The washing conditions,including detergents,light,pH,and ionic strength,can affect the aggregation and dissolution behavior of silver nanoparticles,thereby affecting subsequent environmental processes and negatively affecting aquatic organisms and ecosystems.In this review,relevant domestic and foreign research literature were summarized to explore the effects of different washing conditions on the aggregation and dissolution behavior of silver nanoparticles,and to reduce the environmental risks brought by silver nanoparticles.The characteristics of laundry wastewater were summarized.Based on the characteristics of water quality,the influences of different washing conditions on the aggregation and dissolution behavior of silver nanoparticles in laundry wastewater were summarized.The single or combined effects and mechanisms of detergent types,light,pH,ionic strength and other washing conditions in laundry wastewater on the aggregation and dissolution behavior of silver nanoparticles were discussed.According to the mechanism,some suggestions were put forward to reduce the biological toxicity of silver nanoparticles,including reducing the release of silver nanoparticles during washing,and optimizing the treatment of laundry wastewater.Finally,the future research direction of silver nanoparticles in laundry wastewater was prospected,and the follow-up research suggestions were put forward.This review could provide a reference for further research on the migration and transformation of silver nanoparticles in laundry wastewater or other polluted water bodies,and also provide a way to reduce the release of silver nanoparticles in the washi
