【摘要】：近年来,人工碳纳米材料在诸多领域都显示出了广泛的应用前景,而碳纳米材料产量和使用量的大幅增加也使其环境行为与效应受到关注。碳纳米材料进入环境后,可发生复杂的物理、化学和生物转化,导致其表面电荷、疏水性及表面官能团等理化性质发生显著改变。碳纳米材料的环境转化一方面可导致其胶体稳定性、迁移能力和生物效应发生改变,另一方面可显著影响其富集、输送和转化环境污染物的能力,因此,环境转化决定了碳纳米材料的环境行为及其效应。本文总结了近年来有关人工碳纳米材料环境转化及其效应的主要研究成果,探讨了环境转化影响碳纳米材料环境行为与效应的关键机制和构效关系。
[Abstract]:In recent years, artificial carbon nanomaterials have shown a wide range of application prospects in many fields, and the environmental behavior and effects of carbon nanomaterials have been paid attention to due to the large increase in the production and use of carbon nanomaterials. When carbon nanomaterials enter the environment, complex physical, chemical and biological transformations can take place, resulting in significant changes in physical and chemical properties such as surface charge, hydrophobicity and surface functional groups. On the one hand, the environmental transformation of carbon nanomaterials can lead to changes in colloid stability, migration ability and biological effects, on the other hand, it can significantly affect its ability to enrich, transport and transform environmental pollutants. Environmental transformation determines the environmental behavior and effect of carbon nanomaterials. In this paper, the main achievements on environmental transformation and its effects of artificial carbon nanomaterials are summarized, and the key mechanism and structure-activity relationship of environmental transformation on environmental behavior and effect of carbon nanomaterials are discussed.
